I got the same problem... PermGen in EJB3 client aplication by remote interface. The application is as sample as it can be: -get remote interface of stateless EJB3 (by JNDI) - ask 1000 times to get a Collection of 10 EntityBeans.
After 255 there is OutOfMemory: PermGen. JVM options changes nothing (eventualy more PermSpace => longer run). The reason looks like the Javassist create lazyinitializer classes for every EntityBean retrived from the server. So: When I debug on server-side, I got before sending Entity to client: I got: myEntity[0].id=143534 myEntity[0].flow=<FlowEntity_$$_javassist_7> 13434 ... myEntity[0].user=<UserEntity_$$_javassist_15>... myEntity[0].stage=<StageEntity_$$_javassist_17>... And every remote call the class names (name)_$..._javassist_(index) got the same indexes (7,15,17) on server side (end every entity in returned collections of entities) But when I debug on client site - after return from remote call - the indexes of all returned entities are different (Each next increments index). So after first call I got: myEntity[0].id=143534 myEntity[0].flow=<FlowEntity_$$_javassist_0>... ... myEntity[0].user=<UserEntity_$$_javassist_1>... myEntity[0].stage=<StageEntity_$$_javassist_2>... ... myEntity[1].id=143534 myEntity[1].flow=<FlowEntity_$$_javassist_3> ... myEntity[1].user=<UserEntity_$$_javassist_4>... myEntity[1].stage=<StageEntity_$$_javassist_5>... ... After secund call: myEntity[0].id=143534 myEntity[0].flow=<FlowEntity_$$_javassist_6>... ... myEntity[0].user=<UserEntity_$$_javassist_7>... myEntity[0].stage=<StageEntity_$$_javassist_8>... ... myEntity[1].id=143534 myEntity[1].flow=<FlowEntity_$$_javassist_9> ... myEntity[1].user=<UserEntity_$$_javassist_10>... myEntity[1].stage=<StageEntity_$$_javassist_11>... ... And so on... ... and permGen after 260 iterations... I have not idea, how to deal with that...
