Today I had some troubles to debug a Java class in Eclipse.
The debugger didn’t stop at my breakpoints.
To solve this issue I have editted my debug configuration in eclipse.
Put the following in your vm arguments to increase the initial and max heap size.
-Xms512M -Xmx512M
Other ideas are Welcome!!

Do you use Sun VM 1.6? If so make sure you use the latest version – there are reported bugs with older 1.6 JVMs.

Seriously… ffs, I have struggled with this issue for like 3 days now, rebuilding workspaces left and right switching JDK’s, configuring classpaths and even reverting back to older Eclipses.
Min and Max mem settings seem to solve the problem……….. im really mad right now
Thx for the info XD.
