      Description

      Doing local debugging of an application on TomEE 1.7.0 using JAX-RS and EJBs, after unloading, I traced back strong references via the jaxrs-field-proxy-map. Some of these got fixed in CXF 3.0 by this commit:
      https://github.com/apache/cxf/commit/d012b94b94686dc98762b919a60b765be5b0b3df

      However, org.apache.cxf.jaxrs.model.AbstractResourceInfo's addToMap() creates a HashMap instead of a WeakHashMap, so strong references to fields still remain and prevent GC.

      In order to validate fixing these issues, I also had to modify my thread pooling to see that the last remaining strong reference, via a Stateless pool thread's threadLocals, got removed:
      <Container id="myStatelessContainer" type="STATELESS">
      MaxSize = 0
      StrictPooling = false
      </Container>
