> MemoryLeak when stopping and restarting Felix
> ---------------------------------------------
>
> Key: FELIX-1170
> URL: https://issues.apache.org/jira/browse/FELIX-1170
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: felix-1.2.1
> Environment: Atlassian JIRA
> Reporter: Jed Wesley-Smith
> Assignee: Karl Pauls
> Fix For: felix-2.0.0
>
> Attachments: BundleProtectionDomain.java.FELIX-1170.patch
>
>
> There is a memory leak caused by a strong reference from the
> BundleProtectionDomain to a bundle and Felix.
> The problem is that a URLClassLoader gets its AccessControlContext from the
> stack - AccessController.getContext() calls
> AccessController.getStackAccessControlContext() which is basically arbitrary
> at the time.
> In our case we have a ServletFilter plugin that is being loaded by Felix.
> When a JasperLoader (a URLClassLoader) is created to load a JSP it inherits
> the BundleProtectionDomain as part of its AccessControlContext. If we later
> shut down Felix, it cannot be GC'd due to this reference.
> For our purposes we have tested making the m_felix and m_bundle weak
> references and have verified that it does indeed fix the problem.
