-----------------------------------
The fix for jassist-163 doesn't look thread safe.
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.
