Subject [jira] [Created] (CXF-7166) NullPointerException at org.apache.cxf.common.jaxb.JAXBUtils.createJAXBContextProxy with IBM-JDK 8

-----------------------------------

             Summary: NullPointerException at org.apache.cxf.common.jaxb.JAXBUtils.createJAXBContextProxy
with IBM-JDK 8
                 Key: CXF-7166
                 URL: https://issues.apache.org/jira/browse/CXF-7166
             Project: CXF
          Issue Type: Bug
          Components: JAX-WS Runtime
    Affects Versions: 2.7.18
         Environment: All os
CXF in conjuction with JBoss EAP 6.4.10 and EAP 7.1.0
IBM-JDK8
            Reporter: Rebecca Searls


This phenomenon occurs when Full GC happens before calling CachedContextAndSchemasInternal#getContext()
in a constructor of org.apache.cxf.common.jaxb.JAXBContextCache$CachedContextAndSchemas. WeakReference<JAXBContext>
context inside org.apache.cxf.common.jaxb.JAXBContextCache$CachedContextAndSchemasInternal
is cleared at the Full GC then CachedContextAndSchemasInternal#getContext() returns null.

This issue is reproducible with IBM-JDK 8 but not with OpenJDK or Oracle JDK 8.
