[jira] Updated: (GERONIMO-2416) ProxyMethodInterceptor should work
with classes that have start,stop methods
[ http://issues.apache.org/jira/browse/GERONIMO-2416?page=all ]
Matt Hogstrom updated GERONIMO-2416:
------------------------------------
Fix Version/s: 2.0
(was: 1.2)

> Key: GERONIMO-2416

> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: kernel
> Affects Versions: 1.2
> Reporter: David Jencks
> Assigned To: Dain Sundstrom
> Priority: Critical
> Fix For: 2.0

> jetty6 components usually have lifecycle methods start,stop, and possibly others. If we write a gbean extending these objects ProxyMethodInterceptor blows up with an ArrayIndexOutOfBoundsException (-1). I don't understand why this happens, and there might be a different cause, but the gbeans that have this problem all extend jetty objects with start methods.
> A really bad workaround that lets the server start is this patch:
