[Jersey] PermGen Memory Leak in Tomcat

Hello,

I am using Jersey 1.9.1 with spring to create a rest web service hosted in
Tomcat. When the web application is undeployed Tomcat logs a warning that
the application has created a ThreadLocal and not removed it:

SEVERE: The web application [/sandbox] created a ThreadLocal with key of
type [null] (value
[com.sun.jersey.core.impl.provider.xml.ThreadLocalSingletonContextProvider$1_at_])
and a value of type
[com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl] (value
[com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl_at_f76983]) but
failed to remove it when the web application was stopped. This is very
likely to create a memory leak.

After deploying and undeploying the app several times Tomcat runs out of
PermGen space.

The application follows the pattern in this example.

Any advice on how I can cause Jersey to clean up the Thread Locals on
undeploy would be nuch appreceiated.

Thanka a lot.
