[Ikvm-developers] possible ikvmc AWT deadlock

[Matthias D. <mat...@go...>]

Hello,

hope this is the right section to post this issue, so I will just jump into
it.

I did download the latest jDownloader source, exported it and recompiled it
to a .net library with ikvmc.
This works fine and jDownloader is running, however on certain
circumstances the gui will freeze completly (for example opening the
settings).

I did some further analysis and came up with a stacktrace on the
"deadlocked" awt thread:

Running it via "ikvm -jar jDownloader.jar" however does work and you get to
see the settings panel but I did recognize the following exception:

cli.System.MissingMethodException: Methode nicht gefunden: "Void

So maybe they go in hand (but I don't think so)


To reproduce the issue:

1. http://jdownloader.org/knowledge/wiki/development/get-started
2. export the JDownloader Project as runnable jar with the extract option
(using eclipse in my case)
3. Get the latest developer snapshot from ikvm (or you will run into a
stackoverflow I did report)
4. Run "ikvmc.exe" -classloader:ikvm.runtime.ClassPathAssemblyClassLoader
jDownloader.jar
5. Run the generated jDownloader.exe file, wait for jDownloader to start
successfully and click menu=>settings=>settings


I don't need this to be fixed as I'm don't using the jDownloader Gui
anyway, It would be nice for debugging though.
Also I did some "hacky" workaround because of this issue to make the swing
thread resposible again:

            swingThread.interrupt();
            var newEventQueue = new EventQueue();
            var put =
(EventQueue)AppContext.getAppContext().put(AppContext.EVENT_QUEUE_KEY,
newEventQueue);
            var toolkit = java.awt.Toolkit.getDefaultToolkit();
            var eventQueue = toolkit.getSystemEventQueue();
            Debug.Assert(newEventQueue == eventQueue);

I don't know if this is good or bad but in my situation this works and is
all I need.
And as little bonus after some time the gui is responsible again?!

Hope this helps somebody to fix the issue, if there is anything other I can
do to help (stacktraces, minidumps or something like that), just let me know

Regards,
Matthias
