Rebecca Searls created CXF-7166:
-----------------------------------
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.
