Hi all,
we are using OpenJPA in our osgi environment (Apache Felix) and got some (non-deterministic ) ClassNotFoundExceptions caused by already closed jars. This occurs only when the persistence bundle we are using is redeployed. We mentioned that the PCRegistry.register method is invoked when our Entity-classes get instantiated. This works as expected. The meta data map of the Registry is filled and successfully passed through the MetadataRepository. After a redeployment this happens again and again so the map of registered metas in the PCRegistry grows and grows and contains classes referencing already disposed classloaders. When the registered metadata get used this can cause ClassNotFoundExceptions when an outdated classloader is access. I assume that this happens non-deterministic because the order of the data to iterate over isn't predictable. Is this diagnostic right? Should PCRegistry.deRegister be called when a bundle is stopped before update? Can this be done by any configuration? Thank's so far, Dirk Rudolph T-Systems Multimedia Solutions GmbH Organisationseinheit CCS Dirk Rudolph Software-Entwicklung, OCJP Hausanschrift: Riesaer Straße 5, 01129 Dresden Postanschrift: Postfach 10 02 24, 01072 Dresden +49 351 2820-5363 (Tel) E-Mail: dirk.rudo...@t-systems.com <mailto:mdirk.rudo...@t-systems-mms.com> Internet: http://www.t-systems-mms.com <http://www.t-systems-mms.de/> T-Systems Multimedia Solutions GmbH Aufsichtsrat: Klaus Werner (Vorsitzender) Geschäftsführung: Peter Klingenburg, Dr. Jens Nebendahl Handelsregister: Amtsgericht Dresden HRB 11433 Sitz der Gesellschaft: Dresden Ust-IdNr.: DE 811 807 949
