>             Project: Felix
>          Issue Type: Bug
>          Components: Framework
>    Affects Versions: framework-5.0.1, framework-5.6.1
>         Environment: all
>            Reporter: Nicolas Roduit
>            Assignee: Karl Pauls
>             Fix For: framework-5.6.4

>
> This a workaround of the issue that I submitted on https://bugs.openjdk.java.net/browse/JDK-8054639
> The Java Web Start classloader doesn't support to have anonymous classes or enum within the shutdown hook.
> The patch below allows to stop all the bundles correctly when calling  m_felix.stop() in the shutdown hook. Otherwise the framework throws an exception and do not call the bundle stop. This is a problem when each bundle write its preferences or state during the stop method.
