             Summary: Perm heap bloat
                 Key: WELD-1058
                 URL: https://issues.jboss.org/browse/WELD-1058
             Project: Weld
          Issue Type: Bug
          Components: GlassFish Integration, Performance and Scalability
    Affects Versions: 1.1.2.Final
            Reporter: z xj


Synopsis:
The proxy classes generated at application start time are kept after stopping application. It will result in perm heap bloat if application's start/stop are repeated.

Version:
WELD 1.1.2

Details:
The current RI uses javassist to generate the corresponding proxy class of Principal, UserTransaction, ValidatorFactory and Validator at application start time. Javassist load those proxy classes via system's class loader and that class loader is not discarded after stopping application, therefore those proxy classes remain there. At application development phase, repeating application's start/stop will lead to memory leak with this behavior.
