      Description

      Scenario - note that this works fine with Java 5, but on Java 6 we have:

      • A jsp instanties a class from bundle A with the new operator
      • JSP is loaded - everything is working fine
      • Bundle A is uninstalled
      • JSP invocation results in NoClassDefFoundError (which is expected)
      • Bundle A is installed
      • JSP is invoked and as soon as the new operator is called a NoClassDefFoundError is called

      It seems that Java 6 behaves differently than Java 5: The jsp can be loaded and executed, but as soon as the class from Bundle A is used, Java 6 memorieses that the class was gone inbetween and it is not possible to update this state somehow. All involved classloaders are not queried anymore
