Description

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.
