             Summary: Performance bottleneck on Javassist
                 Key: AS7-5127
                 URL: https://issues.jboss.org/browse/AS7-5127
             Project: Application Server 7
          Issue Type: Bug
          Components: JPA / Hibernate
    Affects Versions: 7.1.2.Final (EAP)
         Environment: Sun/Oracle JDK 1.6_32, Linux 64b
            Reporter: Alessandro Lazarotti
            Assignee: Scott Marlow
             Fix For: No Release

The method javassist.util.proxy.RuntimeSupport.find2methods has a synch block, called indirectly by ProxyFactory.createClass(). It is a strong bottleneck for frameworks as Hibernate which can use it several times in a large set of data. 

Javassist 3.17.0-GA fixes it. AS7 should update its current javassist version.
