I just tried a very simple bundle with trunk and see classes unloaded: ( note - I customized shell.tui to force a couple of GCs per command ) ========================================================== -> ps START LEVEL 1 ID State Level Name [Loaded java.util.TreeMap$3 from /home/stuart/Tools/j2sdk1.4.2_15/jre/lib/rt.jar] [ 0] [Active ] [ 0] System Bundle (1.1.0.SNAPSHOT) [ 1] [Active ] [ 1] Apache Felix Shell Service (1.0.0) [ 2] [Active ] [ 1] Apache Felix Shell TUI (1.1.0.SNAPSHOT) [ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.1.0.SNAPSHOT) -> ps START LEVEL 1 ID State Level Name [ 0] [Active ] [ 0] System Bundle (1.1.0.SNAPSHOT) [ 1] [Active ] [ 1] Apache Felix Shell Service (1.0.0) [ 2] [Active ] [ 1] Apache Felix Shell TUI (1.1.0.SNAPSHOT) [ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.1.0.SNAPSHOT) -> install file:/tmp/foo.jar Bundle ID: 4 -> ps START LEVEL 1 ID State Level Name [ 0] [Active ] [ 0] System Bundle (1.1.0.SNAPSHOT) [ 1] [Active ] [ 1] Apache Felix Shell Service (1.0.0) [ 2] [Active ] [ 1] Apache Felix Shell TUI (1.1.0.SNAPSHOT) [ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.1.0.SNAPSHOT) [ 4] [Installed ] [ 1] foo (1.0.0.SNAPSHOT) -> start 4 DEBUG: WIRE: 4.0 -> foo -> 4.0 DEBUG: WIRE: 4.0 -> org.osgi.framework -> 0 [Loaded foo.internal.ExampleActivator] STARTING foo REGISTER foo.ExampleService [Loaded foo.ExampleService] [Loaded foo.internal.ExampleServiceImpl] -> ps START LEVEL 1 ID State Level Name [ 0] [Active ] [ 0] System Bundle (1.1.0.SNAPSHOT) [ 1] [Active ] [ 1] Apache Felix Shell Service (1.0.0) [ 2] [Active ] [ 1] Apache Felix Shell TUI (1.1.0.SNAPSHOT) [ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.1.0.SNAPSHOT) [ 4] [Active ] [ 1] foo (1.0.0.SNAPSHOT) -> uninstall 4 STOPPING foo [Loaded org.apache.felix.framework.Felix$RefreshHelper] [Unloading class foo.internal.ExampleServiceImpl] [Unloading class foo.ExampleService] [Unloading class foo.internal.ExampleActivator] -> ps START LEVEL 1 ID State Level Name [ 0] [Active ] [ 0] System Bundle (1.1.0.SNAPSHOT) [ 1] [Active ] [ 1] Apache Felix Shell Service (1.0.0) [ 2] [Active ] [ 1] Apache Felix Shell TUI (1.1.0.SNAPSHOT) [ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.1.0.SNAPSHOT) -> ========================================================== the foo bundle installs a simple service with the OSGi framework. if you can provide a simplified testcase that shows a bundle not unloading, please open a JIRA issue and attach the files needed to recreate it so we can investigate. ( diagnosing the issue is much faster when we have a testcase ) alternatively, if you want to diagnose it yourself, I'd suggest using a heap profiling tool to find out what's holding on to your application classes - and see what's different between other frameworks.
