JSF/KB memory leak ------------------ Key: JBIDE-17866 URL: https://issues.jboss.org/browse/JBIDE-17866 Project: Tools (JBoss Tools) Issue Type: Bug Components: jsf Affects Versions: 4.2.0.Beta3 Reporter: Fred Bricon Assignee: Viacheslav Kabanovich Fix For: 4.2.0.CR1 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 !http://content.screencast.com/users/fbricon/folders/Jing/media/218ef77b-df6a-44f8-864d-f6d6fb8999e7/00000001.png!
