Andi Huber updated ISIS-1754:
-----------------------------
Description:
Skinny-war and fat-war deployments work as long as the JEE server is in a
state, where DataNucleus (5.1) was not yet loaded by any class-loader. (e.g.
nothing deployed, and fresh boot of JEE server)
Once DN is loaded by the JEE any subsequent deployment could fail with
org.datanucleus.metadata.InvalidClassMetaDataException under special
circumstances:
* a persistence-capable class (A) inherits from a super class (S), while A is
'skinny-war deployed' and S resides in a container shared library
