Problem conclusion

  • The refactored items that are not in the cached list are
being cloned and the output stream being used for
serialization was not reset causing incorrect objects. Because
of this the versioning context on the actual objects were not
saved causing a NPE.

For install/uninstall instructions, please check the README
file which can be downloaded together with the iFix file.
