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:
- edit JRE being used
- edit 'Default VM Arguments' line
Fixes it for me!
