-------------------------------
Attachment: TestDerbyLeak.java
> Memory leak when shutting down Derby system
> -------------------------------------------
>
> Key: DERBY-5963
> URL: https://issues.apache.org/jira/browse/DERBY-5963
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.5.3.0, 10.9.1.0
> Environment: Embedded Derby
> Windows 7
> java version "1.6.0_31"
> Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
> Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)
> Reporter: Igor Sereda

> I am using an embedded Derby on a server within OSGi environment, as a
> private library in my bundle. When the bundle is deactivated, I stop Derby
> database (with jdbc:derby:;shutdown=true;deregister=true URL)
> But although otherwise the database is released, an instance of
> ContextManager stays in memory due to a leaked reference in a ThreadLocal
> variable (from ContextService, I presume). The instance of ContextManager is
> a big deal, because it also holds the whole page cache in memory (40MB), and
> also, via class loader, holds whole my OSGi bundle too.
> Please let me know if you need any information on reproducing this problem.
> Thanks!
