I fixed this - it was due to proxies being initialized from endLoadingCollections() calling endRead() on a Set of objects which overrode hashCode() and equals() to call the hashCode/equals of another proxied object.

at java.util.HashMap$HashIterator.remove(HashMap.java:755)
Attached sources contain all necessary to run test. You will need Oracle JDBC.
1. Create new database user (optional, you may use existing schema)
2. execute init.sql from sources archive on the database
3. fix Test.java (HOSTNAME, SID, USERNAME and PASSWORD in the JDBC database URL).
4. Run test
