Subject [jira] Resolved: (CXF-850) performance of repeated calls to jaxws.Service.createPort is poor, jaxb context is created every time
Date Thu, 26 Jul 2007 16:26:04 GMT

     [ https://issues.apache.org/jira/browse/CXF-850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daniel Kulp resolved CXF-850.
-----------------------------

    Resolution: Fixed

The CacheMap is a special kind of WeakHashMap.   It's designed to hold onto the target object
(in this case the JAXBContext) as long as anyone strongly references any of the keys (in this
case, the Set<Class<?>>) that were used to retrieve it.   It's perfect for this.
  To make it work, all that needed to be done was the JAXBDataBinding instance in the service
port just needs to strongly hold onto the Set<Class<?>> that was used as the key.
  When the port goes away, the set is no longer strongly referenced, it goes away, the cache
clears, etc...

In any case, it's committed now.  :-)
