Re: rmi classloading exceptions when launching 1.1

At worst case adding duplicate jars with increase the size 1-1.5 megs.

Thank you for listening to my conversation with myself :)

Ok playing around I think I figured out the problem, but its going to be tricky getting a correct solution. The issue is the following...
I'm supporting both V1 and V11 there are several jars at the same versions between 1.0 and 1.1 namely (mx4j, commons-logging, spec jars, etc..). Now I wanted to avoid repacking these jars multiple times so I pushed these into a common runtime plugin, where the V1 and V11 runtime bundles would depend on. The issue seems to be that the common plugin is where the de-serialization is happening and this bundle has no visibility to the class causing the CNF exception since the class is a V11 specific jar. As soon as I put a dependency on the V11 runtime bundle, the problem was resolved. However this (1) introduces a circular dependency between runtime.common and runtime.v11, and (2) Following the same pattern I would have to put a dependency on runtime.common to runtime.v1, which of course introduces the problem of multiple version of clasess in the same cp.
So I'm going to play around with it some more but it may come down to that I am forced for at least a subset of the "common jars" to ship duplicates to get both V1 and V11 working and without introducing any circular dependencies or multiple versions of classes in the same bundle classpath.

Shoot, I was hoping a stand-alone test case would fail as well, but it doesn't. :( So the issue is specific to invoking this within eclipse bundles.

I'm running into the following exception when launching 1.1 within eclipse and I can't figure out what is the root cause. The actual launch of the server is ok but the plugin code checks for when geronimo is fully started by checking the kernelFullyStarted attribute. I'm hitting the following set of exceptions below in my call to...
AbstractNameQuery query = new AbstractNameQuery (PersistentConfigurationList.class.getName()); 
Set configLists = kernel.listGBeans(query);
IIRC this is the same set of exceptions when people launched eclipse in a 1.5 JVM, however in this case I'm launching in 1.4 and I verified that the 1.0 support still works when calling the same code... I verified the G 1.1 jars I'm repackaging are the same as the ones inside the 1.1 image I'm launching but I'm hitting this now every single time. :( 

Does anyone have any ideas???
