On windows, using the msi-installer, the version is always 16.0.0 so a new version can't be installed unless removed first.
Tried to upgrade from 3.6 to 3.7 and wasn't allowed.

Version for msi 16.0.0:

Hello, first of all that's a awesome tool/project.

I've looking for a tool like this for windows when I found SDKMan. Can the JDKMon works like SDKMan for windows or it's like just for show jdk installed in machine?

Enable JDKMon to search in multiple folders for installed JDK's

Many people are just using JDK releases. What do you think of an option to make that the default and an opt-in for ea releases?

Would like an option, maybe even default, to autostart with the computer/windows.

its a bit of a treasure hunt to find the download jdk window if you have already openeded it once.

currently I have to restart JDKMon after having moved a window in front - its faster than trying to find it :)

would be great if jdkmon would bring windows/dialogs to the front when invoked via menu.

I just downloaded package from blogspot page:
jdkmon_17.0.18-1_amd64.deb
and installed it.

When i run it from launcher nothing happens.
When i run it from cmd i get this:

Hello, I do not see a license for this program.
So which license is it licensed under ?

When started, it takes tens of seconds, almost a minute, to show a window. On a 3960X 24-core Threadripper with 64G RAM and Nvidia 2070 SUPER.

This window, however, is unresponsive to clicks. I managed to get one right-click out of it among several tries (and showing a context menu), but it usually only started to seize the mouse for the whole desktop. After trying to start it from the command-line, this is printed out:

Sep 09, 2022 4:40:07 PM com.sun.javafx.application.PlatformImpl startup
WARNING: Unsupported JavaFX configuration: classes were loaded from 'unnamed module @2dd61f5b'

(JDKMon:815907): Gdk-WARNING **: 16:40:26.926: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

Ctrl-C wasn't working in the terminal and no mouse input was possible anymore. One pkill later the window died, leaving an "empty" window shell behind, including a defunct systemtray icon. Still no mouse on the whole desktop. After switching to console (away from GUI Desktop altogether), a kill -9 finally ended the misery.

The window that showed up did look pretty, though. Quite a pleasant surprise.

It seems to come with it's own Java runtime, right? Haven't tried to run it with one of the installed, known good ones though.

I was thinking about using JavaFX for internal GUI projects, but yeah, that was a kind of cold shower right there and then. Yet I still like the looks of JDKMon. ;)

This behavior is for me as user unpleasant.

In notification are for me (on Windows 10) some graphic glitches.

Please, see attached screenshot of notification bellow (glitches are marked red):

For not directly downloadable JDK distros (tooltip is now with "No direct download, please check website") would be nice has feature(s) copy URL of web site/open web site for given JDK distro in default browser.

Status now (only):

This problem is ONLY in this case (my OS is Windows 10, version JDKMon is 17.0.0.0):

1. 2x click on shortcut "JDKMon" on desktop for launch JDKMon
2. close the window "JDK Mon" or leave it open (does not affect the issue)
3. on tray icon for JDKMon from context menu (right click) to select item "Download a JDK"
4. in opened dialog "Download a JDK" on top is missing text "Bundled with FX" for given checkbox <- issue (see screenshot bellow)

Important note:
after close dialog "Download a JDK" and next open the given dialog this issue does not exist next already

Screenshot (for typo "Operatingsystem I send PR already"):

macOS DMG looks to be damaged - .pkg works fine.

Nothing obvious on the command line ./JDKMon same error dialog.

Suggestion to add more default search paths now that multiple can be added.
For example: C:\Program Files\Zulu on windows, but there are certainly more, for adopt open jdk etc.

If multiple JDK's are found, detect and display the currently configured JDK in JAVA_HOME.

Adding a search path that adds more jdks doesn't resize the window if open:

Using windows. jdkmon 3.7

As explained in this issue, the Oracle JDK installers for Windows (and possibly for macOS too) now shims only 4 binaries in a folder called java_home and uses such directory as the bin that is appended to PATH.

An interesting feature for JDKMon is to offer the user an option to clean PATH and JAVA_HOME, and then allow the user to select which JDK they actually want, and then shim the binaries, append the folder containing the shims in PATH, and point JAVA_HOME to that particular JDK only.

This would potentially take JDKMon to the next level as a cross-platform JDK Switcher.

Hey Gerrit,

I tried the basic git clone, open IntelliJ, run... and it fails. JDK 17 installed locally.

Also tried from the console with gradlew run and it also fails.

I'd love to give this a try and start thinking about JDK Switcher.

Hi. Thanks for this application.

I'm using Manjaro Linux and I've hit on some weird edge case: running the application with java -jar JDKMon-linux.jar nothing happens. However, when I run with GTK2, it works just fine: java -Djdk.gtk.version=2 -jar JDKMon-linux.jar

I'd like to suggest adding this property in the ReadMe, in case someone tries to run your application and have the same issue.

After click on download JDK distro is dialog "JDKMon Download Info" (and this dalog has focus) shown under "main window" JDK Mon (this window is always on top). For me was whole dialog "JDKMon Download Info" under "main window" JDK Mon - this is not very user firendly.
May be related with fix for issue #24.

My OS is Windows 10.

In the Windows 10 version of 17.0.6 there is a checkbox that is missing a label.

Maybe it would like to automate it somehow ...

Suggestion:
Add a way to add search paths from the main window. Currently you have to locate the tray icon and right click it to add more search paths. If you already have the main window open it would be nice to be able to add more there.
Actually all right click options would be nice (rescan).

After installing (windows, msi installer) nothing happens. User expectation is usually that the app is launched or at the very least have an app shortcut available somewhere (meny and or desktop).
Now you have to open an file explorer, go to c:\program files\jdk mon and launch it yourself. No launcher shortcut in the menu or desktop.

Sdkman is quite the popular tool for keeping JDK installations up to date. It'd be great if JDKMon supported scanning directories managed by Sdkman.

It provides builds for Valhalla, Loom, master, and a few others that would be great to be included.

see screenshot

I would use this text "* Marks currently selected JDK (in JAVA_HOME)" somewhere in window (or You have better idea?).
I think it would be useful.
