> 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.
