>                 URL: https://issues.apache.org/jira/browse/SLING-1435
>             Project: Sling
>          Issue Type: Bug
>          Components: Commons
>    Affects Versions: Commons ClassLoader 1.1.4
>            Reporter: Carsten Ziegeler
>            Assignee: Carsten Ziegeler
>             Fix For: Commons ClassLoader 1.2.0

> 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
