Max Rydahl Andersen commented on JBIDE-17866:
---------------------------------------------

what kind of savings does these changes result in ? 

And we should resolve this with details for CR1 and open separate one for future 4.3 work.

> Playing with m2e 1.6 on my new MBP, I imported the [wildfly|https://github.com/wildfly/wildfly] [projects|https://github.com/wildfly/wildfly-core] in my workspace, then deleted everything.
> Before import heap was at ~80MB, after th 135 projects and forcing GC, it doesn't go down 280MB. I then took a heap dump (https://www.dropbox.com/s/gmxy6ofdwrtb8g2/java_pid14384.0002.hprof.zip), loaded it into Eclipse Memory Analyzer and looked for org.jboss.* components.
> It seems we retain many XModelMetadataIpl, JSF2Project, KbProject instances and a bunch of other JBT classes, that should be cleaned up when projects are deleted from workspace
