PluginPoint.XXX.
There is (I think) some generic code in v2 that inserted "bean-methods" (in
other monitoring items there are other strings) between the
<app-name>.<module-name>.<bean-name> and the stringified method signature:
server.applications.ejb-flush-testApp.ejb-flush-test-ejb\.jar.A2.bean-methods.create-java\.lang\.String.dotted-name

CallFlowInfo is (was?) a generic monitoring interface:

Will both classes be marked as @ManagedObject?
