Debugging a SWT application causes all GTK applications to freeze

I have a SWT application that I am debugging using remote debugging in eclipse. If I set a breakpoint inside the SWT application event handler, my desktop with holes freezes. I can still switch to a text console by Strg+ Alt+ Fx. If I kill the SWT application from the console, everything will work.

Since this only happens when the breakpoint is inside the event handler, I highly suspect that the SWT blocks the event loop, causing everything to freeze. I guess there is some magic setting for SWT to “separate” applications, so I can debug correctly, but I cannot find it.

This is a known issue with custom widgets that have the capture of an X-pointer and not releasing it. The most common solution is to launch your internal eclipse on another display. I use Xvnc because I run into this problem all the time, but other examples are XNest .

I saw people trying to use -Dsun.awt.disablegrab=true. I don't know if this works or not.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=20006 for a long discussion of the problem and what people have tried.
