Mark Zeldis commented on FELIX-4837:
------------------------------------
Yeah, it's up to you guys. It's definitely a weird one, but for whatever
it's worth this is 100% the solution. I've been using it in my product
since the last update with zero issues.
> Workaround for JNLPClassLoader in ShutdownHook

> Key: FELIX-4837
> URL: https://issues.apache.org/jira/browse/FELIX-4837
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: framework-5.0.1, framework-5.6.1, framework-5.6.4
> Environment: all
> Reporter: Nicolas Roduit
> Assignee: Karl Pauls
>
> 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.
