Refreshing highly dependent bundles crashes Felix but not Equinox

dustin_dustin.schultz Feb 15, 2012 11:14 AM

Hi,

Whenever a highly dependent bundle is refreshed (e.g. after a feature install), Felix proceeds to try and refresh all related bundles and always fails with a random ClassNotFoundError. The class not found is different each time.

To reproduce, with a fresh install, wait until all bundles are resolved and blueprints are created, then refresh spring-core. If you're using Felix (the default) it will eventually lock up or commands won't work (e.g. refresh is not a command). Do the same with Equinox and no problems.

In the example below, 78 is Spring Core

karaf@root> refresh 78

Command not found: refresh

Killing the process is required at this point.

I've tried adjusting the JVM memory parameters as well but that does not seem to have any affect.

Is this a known issue? I could only find this: https://issues.apache.org/jira/browse/FELIX-3153 which says it was not reproducible.
