Subject [jira] Resolved: (GERONIMO-5279) search-plugins, install-library deploy command fails with NoClassDefFoundError

Jarek Gawor resolved GERONIMO-5279.
-----------------------------------

         Assignee: Jarek Gawor
    Fix Version/s: 3.0
       Resolution: Fixed

Committed fixes for this problem in revision 941340. The gbean proxies did not quite work
in OSGi environment. Each proxy required access to some cglib classes but not every bundle
was importing the cglib packages. To fix this, when a proxy is created, a proxy classloader
is constructed that can delegates the calls to the original classloader and a classloader
that has access to the cglib classes.

> Executing search-plugins, install-library deploy command fails with NoClassDefFoundError.
Looks like the gbean proxying code needs to be fixed.
> Example:
> bin/deploy -u system -p manager install-library /home/gawor/.m2/repository/org/apache/felix/org.osgi.service.obr/1.0.2/org.osgi.service.obr-1.0.2.jar
> {code}
