>    Affects Versions: EJB 3.0 RC9 - FD
>         Environment: Linux Gentoo 2.6.18, JVM 1.5.0.08, 1.5.0.09, amd64

> 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 (List) 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...
