Mattias Jiderhamn commented on CXF-6458:
----------------------------------------
This seems to be a [known limitation of the JAXB
API|https://java.net/jira/browse/JAXB-1000]. Issue claims you can avoid the
problem by explicitly closing the Unmarshaller, but I haven't tried that myself.
> CXF 3.1.0 memory leak (Tomcat)
> ------------------------------
>
> Key: CXF-6458
> URL: https://issues.apache.org/jira/browse/CXF-6458
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.1.0
> Reporter: neil walker
>
> I have created a CXF project using wsdl2java, make no changes (i.e. blank
> project) I deploy it to Tomcat 7 or 8. As soon as I click 'stop', without
> even calling it, I am getting SEVERE errors from Tomcat regarding memory
> leaks and inability to close threads. Every time I start/stop I get an
> additional WebappClassLoader (I have done a memory dump and checked using
> Eclipse MAT) for the webapp and it only gets fixed when I restart tomcat.
> Tomcat also reports this using the 'test for leaks' button.
> This originally happened on CXF2.7 so I upgraded to 3, I have also tried the
> very latest JAXB reference implementation.
> The stack trace is as follows:
> org.apache.cxf.workqueue.AutomaticWorkQueueImpl$AWQThreadFactory$1.run(Automati
