It would be nice if MBean to monitor SWT resources is available, so that user 
can check whether there are any SWT resource leaks caused by missing invocation 
of org.eclipse.swt.graphics.Resource.dispose().

This MBean should be created/visible only when monitoring application which is 
using SWT.

When dumping heap as hprof file on remote host, the generated hprof file should 
be transferred to local host and shown on JVM Explorer, so that user can easily 
open it on Eclipse.

When there is no chart on Timeline page on Properties view, there should be a 
button (link) so that user can load chart set just by one click.

addition to selecting packages contained in projects in workspace.

- User guide should be provided as plug-in so that user can read it from the 
menu Help > Help Contents.

- Every dialog, view and editor that are part of JVM Monitor should provide 
context sensitive help.

Scroll bar appears outside the tab on properties view (e.g. CPU, MBeans page). 
It should appear inside the tab, so that tabs won't disappear from screen.

Please issue 30 for information about my setup.

When I monitor the JVM process for eclipse, I can see charts in timeline.

But when I monitor my own app (a console app) while it is in debugging mode, I 
see nothing in the timeline view. 

For my own app while it is running, the threads and memory views are 
continually changing. 

I was able to use add charts button to add a memory chart to timeline view for 
my app. Why didn't the set of charts showing automatically for eclipse come up 
in the timeline view?   It shows Used Memory Heap, loaded Class count, thread 
count, and cpu usage.   

Is it possible to save a configuration of timeline charts to load into another 
timeline viewer?   Ok just found the docs about the save local menu. Perhaps 
when the timeline window has no charts, it could give a hint about how to load 
some charts.

Perhaps the bug I have here is that the default overview set didn't 
automatically load for my own application.

Chart title on Timeline page cannot be changed to longer name.

**How to reproduce

1. start monitoring a JVM and open Timeline page

2. click Configure Chart button, and change chart title to longer name

I started my application for debugging, let it run to a breakpoitn, and it 
shows up in JVM explorer. When I open the Java Monitor view and select the 
application, the Properties window for JVM Monitor says "Monitoring is not 
supported for the selected JVM"

I am running JavaSE-1.6 (jdk1.6.0_18)  c:\program files (x86)\java\jdk1.6.0_18

Also trying jdk1.6.0_22  c:\program files\java\jdk1.6.0_22   Went to my debug 
configurations, launch, and set to alternate JRE jdk1.6.0_22

Tried selecting  C:\Program Files\Java\jdk1.6.0_22\bin\javaw.exe  as java 
executable for the debug default launch for my app.

I attached my Eclipse configuration  
Environment_Eclipse_About_Configuration.2010-11-29

Windows environment variables shows   java_home  C:\Progra~1\Java\jdk1.6.0_21

Path at DOS command prompt didn't seem to include a path to Java, however it 
did have c:\windows\system32\javaw.exe and java.exe...  Version for java.exe 
says Java(TM SE Runtime Environment build 1.6.0_22-b04 and java hotspot 64-bit 
server vm  build 17.1-b03, mixed mode.

So added C:\Progra~1\Java\jdk1.6.0_22\bin  to start of path. 
Changed java_home to   c:\progra~1\java\jdk1.6.0_22

Added to eclipse.ini and restarted eclipse:
-vm
C:\Progra~1\Java\jdk1.6.0_22\bin\javaw.exe

Making this change is now allowing me to "Start Monitoring" on the eclipse 
process.

Changed Debug Launch default environment to jdk1.6.0_22

Now i can profile my app....

Hopefully you can use this info to make a fix for the issue I had clearer.

link to image is missing at FAQ page in user guide documentation that is 
accessible from the menu Help > Help Contents > JVM Monitor User Guide > FAQ

The button Run Garbage Collector is available at Memory tab, but at Timeline 
tab there should be the same button also on the chart where heap memory usage 
is shown.

Some buttons are not correctly disabled when they are not applicable.

 - disable BCI selection on Configure CPU Profiler dialog when monitoring JVM on remote host without loading agent

 - disable Dump heap / Clear / Refresh when monitoring Eclipse itself where JVM Monitor is running or when monitoring JVM on remote host

MBean to monitor SWT resources has been provided by the enhancement #42, but it 
would be nice if there is a dedicated page to show that MBean at Memory page on 
Properties view.
