Unbundle DCEVM from release and update installation instruction to use original installer
Ignore IDE files
Let's remove *.iml, .ide, etc. files from VCS and add them to .gitignore.
Right now anytime I open my IntelliJ I get all those files as modified in changelist.
Hibernate3 support
Was there any reason not to include Hibernate 3 support?

Linkage error in Wildfly because of differences between JasperLoader and ModuleClassLoader.
I don't know how class loaders work. I only have a vague idea. So I'm sorry if I'm not precise with this description. Here I go...
I'm running Wildfly 8.1.0, with JDK 8 Update 05 and HotswapAgent 0.1 Beta 4. I've successfully installed DCEVM 25.5-b02-dcevmlight-58 as an alternative JVM. I've been able to correctly hotswap several classes. However, I've problems when the class that I hotswap is used in a JSP file but has been instantiated from a class stored in WEB-INF/classes/ . Every time that I do that, I got a java.lang.LinkageError.
Testing it is very easy. Create a WAR file with a class that instantiates itself. For example:
package myweb;
public class Test {
private Test () {
}
public static Test create () {
return new Test ();
}
}
Then write a call to myweb.Test.create () in a JSP file and request such JSP from your browser. It's OK. Now edit the class as you want, submit the changes with your IDE and request the JSP again. It will fail and the server will output:
java.lang.LinkageError: loader constraint violation: when resolving method "myweb.Test.create()Lmyapp/Test;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/test_jsp, and the class loader (instance of org/jboss/modules/ModuleClassLoader) for the method's defining class, myapp/Test, have different Class objects for the type myapp/Test used in the signature
It seems that both class loaders, JasperLoader and ModuleClassLoader, keep a different version of the same class. One of them isn't updated properly.
Thank you.

The given magic number 3c21444f is the hex for <!DO, the first 4 bytes of the HTML file. Basically, HotswapAgent tries to parse this file as Java bytecode, which, obviously, fails.
This might be because we keep our HTML templates (and some other non-Java resources, e.g. *.properties) in the src/main/java folder, and they go to WEB-INF/classes in the WAR file.
I think it's a HotswapAgent bug, because on original JDK it runs without problems.
If the fix is simple, you could point me to the place where this should be corrected so I could fix it myself and make a pull request.

extraClasspath, watchResources and autoHotswap should be handled by agent core
Basic hotswap properties are now supported by tomcat/jetty plugin (Tomcat/Jetty classloader bytecode enhanecements). This is not robust enough and should be supported on JVM level without any framework or other preconditions.
New approach is to modify any ClassLoader with hotswap-agent.properties directly. The only presumption it is that it is instance of URLClassLoader and it use URLClassPath ucp property internally. This is true for system classloaders as well as Tomcat/Jetty classloaders.
Spring MVC support (@RequestMapping)
I think HotswapAgent does not support reloading @RequestMapping routes in beans.
I think all that needs to be done is on a bean change with a @RequestMapping annotation is look in the ApplicationContext for all derivations of AbstractUrlHandlerMapping and call initApplicationContext().
You could reload the HandlerMapping beans but you can't just clear the HashMaps in them as the the URLs are only calculated on initialization. You also can't call setApplicationContext as that will think nothing has changed.
I'll look into trying the above unless others have thoughts?
Exceptions when reloading Spring related classes
Hi,
Here are some of the exceptions thrown when I recompile the classes while in debug mode:

I am running this jvm:

Dynamic Code Evolution 64-Bit Server VM (build 24.51-b03-dcevmfull-3, mixed mode)
Bare in mind that the codebase in this application is big (several mlocs). When I clicked compile in 1 class in debug mode, 450 classes where reloaded. Several had similar exceptions.
I would have to run the test again if you want a full and clean log.
Does this look like something that could be an environment/setup issue or is it a bug in the agent?
Thanks!
Add maven-release-plugin
It looks like releases are done manually, and pom in master still has 0.1-beta3 version, and it should have some snapshot version.
Defining pluginPackages causes NPE on start of application
It seems there is a problem of initialization order of the PluginManager, causing the INSTANCE not being initialized when the custom plugins are initialized:

Jetty plugin should support webappDir configuration property
Also test the plugin to support all versions from 4x to 9x (tested by HotswapAgentExamples/plain-servlet with cargo plugin)
Default logging is very verbose
If you're experienced with DCEVM, HotswapAgent is easy to get running.
My only problem with the default is that the logging is a very verbose. I'm having trouble following my own application's logging.
Most of the logging looks like this:
(-1 / -1) (org/hotswap/agent/plugin/jvm/AnonymousClassInfos$AnonymousClassInfoMatcher/org/hotswap/agent/plugin/jvm/AnonymousClassInfos$AnonymousClassInfoMatcher)
{instance class}
- klass: {other class}
{instance class}
- klass: {other class}
I've tried disabling the logging but it appears my LOGGER=warn in a hotswap-agent.properties in my classpath doesn't seem to be picked up.
(BTW: Thanks for a pretty great alternative to JRebel :))

How to use in Maven Project ?
I exported the two settings variable like this :

and maven gave not a valid identifier error. How to use it in maven webapps ?

Statup log should contain Hotswap Agent version information
Glassfish support
Glassfish is based on OSGI.
Currently it does not start at all - error java.lang.NoClassDefFoundError: org/hotswap/agent/PluginManager. This is because of OSGI bundle mechanism, where parent classloader delegation does not work. Look at https://github.com/HotswapProjects/HotswapAgent/blob/master/hotswap-agent-core/src/main/java/org/hotswap/agent/HotswapAgent.java fixJboss7Modules(), this is similar fix for JBoss. On Glassfish, you need to set "org.osgi.framework.bootdelegation" property (see https://blogs.oracle.com/swchan/entry/profiling_glassfish_3_with_jprofiler), but I was unable to do it from HotswapAgent.
Support for hotswap-agent.properties needs to be developed (similar to JettyPlugin, TomcatPlugin).
Test with https://github.com/HotswapProjects/HotswapAgentExamples/blob/master/plain-servlet/run-tests.sh , uncomment Glassfish section.

Rename annotations
I would like to make a recommendation to change the annotations to provide a consistent interface and to make their purposes more clear.
Here are some examples of some different names-- adjustments can be made to the names, but I believe this shows how they can be improved:
@OnClassLoaded = @Transform(define=true)
@OnClassUpdated = @Transform(define=false)
@OnClassFileUpdated = @watcher(filter = ".*.class")
@OnResouceFileUpdated = @watcher()
java.lang.reflect.GenericSignatureFormatError after class reload
Hi,
There are cases (which I can't define completely) in which after reloading a class and trying to use it, a java.lang.reflect.GenericSignatureFormatError exception occurs.
Reloading the application obviously fixes the issue, but what's more is that the class is reload-able and usable.
I'm using HotswapAgent 0.4, tomcat-7.0.54, jdk1.7.0_51

Remove dependencies from parent pom
I think that parent POM should contain only dependencyManagement section where versions are defined. Then each module should use only groupId/artifactId in it's dependencies.
Hotswap in unit tests should use java Instrumentation API directly to swap classes
new method:
PluginManager.hotswap(Map<Class<?>, byte[]> reloadMap)
to allow application code to use Instrumentation.redefineClasses() method directly.
HotswapperPlugin should use this access as well.

HotSwap with DCEVM configured, started but not reloading changes during app execution ( Maven +JFX )
I'm using Netbeans 8 to write sample application based on Maven and Java FX. I want to set up HotSwap with DCEVM and check if it's working with my project.
Sample application
public class FXMLController implements Initializable {
@FXML
private Label label;
@FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
I've installed and configured DCEVM and HotSwap agent.This is my running configuration:
runfx.args=-Xdebug -Xrunjdwp:transport=dt_socket,server=n,address=${jpda.address} -jar "${project.build.directory}/${project.build.finalName}.jar"
jpda.listen=true
Env.MAVEN_OPTS=-XXaltjvm=dcevm -javaagent:c:\TEST\hotswap-agent.jar=autoHotswap=true
I've also cliked "Compile on save" option in netbeans.
This is log from console during app start.

When I'm debuging code and making some changes adding method or something no changes are made. I can apply changes via netbeasn interface but no log from HotswapperPlugin is visible. Is there is any way to make it work? Am I doing something wrong?
Spring plugin - ProxyReplacer dependency
PluginClass must not contain dependencies to any framework specific classes. If launched in multiple classloader envorinment (servlet container), an error occures:
java.lang.NoClassDefFoundError: net/sf/cglib/proxy/Callback
Framework specific code should be run:
- using java reflection with correct classloader
- or via invocation from modified class inside application classloader.
See http://www.hotswapagent.org/how-does-it-work/hotswap-agent-implementation for more information.
There is example project for plain servlet and with spring and hibernate.
Rename distribution and make it get to maven
ExtraPathResourceClassLoaderTest fails (jdk1.7.0_67 on mac)
I downloaded the project, modified the run-tests.sh to point to my local Java installation (/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home). The result is:
-------------------------------------------------------
T E S T S

java.lang.AssertionError: Returned after modification
at org.junit.Assert.fail(Assert.java:88)
The offending line is:
assertNotNull("Returned after modification", classLoader.getResource(tempFile.getName()));
I can provide more information if needed.
Readme states that the patched hotspot file(s) should be placed in "jre\bin\dcevm"
My tomcat was failing to start with the files in that location, and I was prompted to change this to "jre\lib\amd64\dcevm". After moving the files to lib/amd64/dcevm tomcat proceeded to start fine.
[spring] Refresh @Autowired field
Hi
when I add a new attribute annotated with Autowired, the value stills null after refresh. The spring plugin is enable because I see outputs when the bean is reloaded.
Did I miss something or this kind of support is not already provided by the agent?
Thanks!
