Eclipse plugin project: Mac: using SikuliX hotkeys causes java crash

[RaiMan]

Good day,

Here at my work we use a eclipse's plugin (made by us) to operate with sikuli on ours automated tests. Till some time ago we only used Windows OS (running on Windows 7[64], but now we have a Mac OS X (running on version 10.10.2 [Yosmite]) so I was assigned to make this transaction happen.

I'm using Sikuli 1.1.0 (tried with Sikuli 1.0.1 too) and JDK 8. Things are almost 100% but I have a problem with Sikuli's Hotkey...

Everytime I used the assigned hotkeys, it causes java to crash! Searching in the error logs, it seems a problem with a call on the MacHotkeyManager.dylib.

Is there any know solution for this?

---------------
The creation method is as follow:

HotkeyManager.getInstance()._addHotkey(KeyEvent.VK_2, KeyEvent.SHIFT_MASK + KeyEvent.CTRL_MASK, new HotkeyListener() {
                       @Override
   public synchronized void hotkeyPressed(HotkeyEvent e) {
    Display.getDefault().syncExec(new Runnable() {
     public void run() {
      //Ours method call
        }
    });
   }

});

---------------
FYI on the plugin:
- works fine on Win OS
- works fine without the use of the hotkeys
- Sikuli's Debug dosen't give any information before the crash happens.
