I am looking at "8054896: Loading a KeyStore prevents GC of Classloader" and am
now able to reproduce it on my system. I do see the webapp-related classes present in a

are not GC'ed. Is there a good tutorial on this?
Thanks

Hi Max,
If you are able to determine which instance of which classes should
have been garbage collected but weren't, the next step would
be to select one of them and ask jvisualvm to find the
nearest GC root.
That should give you a hint of who is holding a reference to
the instance.
The next step - often harder - is to figure out why.
