There are at least 2 issues here:
* Gmbal needs to have better error checking on the getObjectName method
o This problem is fixed in my current gmbal master, but not in
the current 3.0.0-b004 that everyone is using.
o Gmbal also needs to include a context describing what is was
doing when the failure occurred
* The TypeConverter needs to handle this error as well. It is
failing in the case of an attribute whose value is supposed to be
an MBean, hence an ObjectName. But the attributes of
JVMClassLoadingStatsProbvider are all of type int or long.
o A possible cause for this is an error in fetching either the
parent or the children attributes.
I have added testing of the AMX-specific parts of Gmbal in the current
master.
I'm adding more testing of MOMs created via createFederated now.
Hopefully that will shed some light on this failure.
In any case, I'll be releasing 3.0.0-b005 soon.
Thanks,
Ken.
