Description of problem:
Plugins like Infinispan plugin may fail with

We should rather make sure, that we don't make such incompatible changes. Those classes are "the public api" of the JMX plugin.
Can we add a unit-test to hold this public API of the JMX plugin constant?
Can we change the animal-sniffer to detect changes in the public API of the JMX plugin?
I would truly like to prevent the introduction of further regressiosn of this type.
also ... can we do a code search to identify what other plugins may have regerssed because of this change?
task for the QE countermeasure. https://engineering.redhat.com/trac/jon/ticket/253
i would also like a dev countermeasure included here ...
release branch af6c7aa
Moving to ON_QA since JON 3.1.1 ER2 build is availble - https://brewweb.devel.redhat.com/buildinfo?buildID=228250
dev added an api diff checker to take care of this.
