Richard,
What's I find bizzare is that both modules involved are both compiling
against javax.management.ObjectName, and have *already loaded and used
it*.
It's only when an ObjectName[] is returned through
java.lang.reflect.Proxy that the receiving module barfs—but it already
has loaded that class previously, and it also depends transitively via
a <dependency> on the module supplying the ObjectName[].
That's what makes it so hard to accept it as something other than a bug.
I need a step-by-step instructions on how to work around this issue:
what goes in pom.xml? what goes in a manifest file? In short, what do
I do?
