      Description

      Hi All!

      We encountered a deadlock situation using T5.0.11 under heavy load. Unfortunately we do not have the detailed knowledge about all T5/javassist-secrets to solve this on our own.
      It seems there are two different execution paths resulting in a call to "ClassPool.toClass". In both cases the inner class org.apache.tapestry.internal.services.ComponentInstantiatorSourceImpl$PackageAwareLoader is part of the deadlock.
      On the one hand we have a call to "findClass(ComponentInstantiatorSourceImpl.java:75)" (please see "catalina-40.txt") on the other hand the toClass2 method tries to access this inner class at the same time. But this is only a guess.

      See below both thread dump stacktraces.

      Any hint to solve this problem is highly appreciated.

      Jens
