Summary: Reduce synchronization in AbstractJAXBProvider
Key: CXF-8149
URL: https://issues.apache.org/jira/browse/CXF-8149
Project: CXF
Issue Type: Improvement
Components: JAX-RS
Affects Versions: 3.3.4
Reporter: Scott Sosna
My company discovered that there was excessive blocking occurring which was
tracked down to AbstractJAXBProvider doing synchronizations when checking
various collections. Instead, using ConcurrentHashMaps and other techniques,
those synchronizations are only necessary when the collection in fact needs
modifications, i.e., the first time a specific type is used. After that,
synchronizations are no longer required and multiple concurrent calls don't
start blocking each other.
