System freezes at Debugging [Eclipse IDE 3.7.2-1, Ubuntu 12.04] [message #870749] Wed, 09 May 2012 10:22 Go to next message

Hi,

I'm pretty new to developing Java with the Eclipse IDE but I'm experiencing already a large problem:

When I'm running my programm in Debug-Mode and reach a breakpoint, my whole system freezes and my only option to continue, is to hit the shut down button.

I'm using Eclipse 3.7.2-1 on latest Ubuntu 12.04

Thanks in advance for any help

Sven

Are you by chance debugging UI call-back handling code? Like a menu popup, etc?

If so this is a known GTK issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=20006

As an FYI you do not have to reboot to recover, you can try one of two things:

1) pressing Ctrl+Alt+Backspace to stop your programs and log out.
2) use Ctrl+Alt+F1 to get to a command line and use the kill command on the Eclipse process you are trying to debug. Once you are done press Ctrl+Alt+F7 to get back to your desktop. The advantage of this method is that you do not have to kill Eclipse or lose any work / open programs.

Hi,

I found out it appears to crash just in one of my projects so far.
I catch the action of a JComboBox and therefore got a breakpoint in my handler.
Even CTRL-ALT-Backspace doesn't work anymore then.
Killing the debugging process via tty worked though, thx.
