Hi Jon,

would be great to get some support here, thanks so much. I'm still doing
tests on it. The follwing additional clues I got so far:
- adding a @RequestScoped annotation will make my mini-non-leaking app start
leaking.
(here my test code (Netbeans project):  leak2.zip
<http://tomee-openejb.979440.n4.nabble.com/file/t376354/leak2.zip>   )
- often Lambda Expressions will also introduce leaks (see example in code)
- note, that no instances of the webapp classes are on the heap after a stop
- but the classes are still loaded. (Maybe something triggers some other
(external) instance to be loaded with the webappclassloader...?)
I'm afraid I'm lacking substantial experience with this type of profiling,
so I almost become clueless on what else to test.

I'm on Tomee plume 8.0.0 and OpenJDK 11

Marcus
