JBoss Developer Studio / Eclipse debug ignores breakpoints fix

This week I ran into some of my Java projects where the debugging was ignoring breakpoints in my JBoss Develoepr Studio / Eclipse IDE's. I thought this was maybe just something in JBoss Developer Studio (JBDS), but it appears to be an issue with Eclipse too. 

This was the fix for me, in JBDS /Eclipse:

 

Window -> Preferences -> Java -> Installed JRE's:

• edit JRE being used
• edit 'Default VM Arguments' line
• -XX:+UseParallelGC

Fixes it for me!
