Hi,
I am quickly scanning this commit and I would like to know if it was not a little bit less intrusive to keep the existing addOperation and search for the return type of the added operations against the target gbeanType. This way, developers do not need to specify the return type of the operations (also, the migration of the existing GBeanInfo could have been avoided). 


After reading GERONIMO-2607, it seems that the goal of the change was  
to have a return type defined within JConsole for the GBean  
operations. It seems that patching JMXUtil.toMBeanInfo would have  
been another implementation approach: while getting the exposed  
operations, the GBean class could be searched for returned types. One  
of the advantages would have been to keep backward compatibility.


Thanks,
Gianny
