Daniel Kulp updated CXF-2741:
-----------------------------
Description:
We have been using CXF RESTFul services for a long time on jboss-4.2.3 with no
issues. When we switched to JBoss 5.1.0.GA, things worked fine at first, but we
noticed that after a short period of uptime, requests began to hang and time
out. Debugging this issue, we tracked it to the synchronized block in

Specifically, this method:
{code}
public JAXBContext getPackageContext(Class<?> type) {
if (type == null || type == JAXBElement.class) {
return null;
}
synchronized (packageContexts) {
String packageName = PackageUtils.getPackageName(type);
JAXBContext context = packageContexts.get(packageName);
if (context == null) {
try {
context = JAXBContext.newInstance(packageName,
type.getClassLoader(), cProperties);
packageContexts.put(packageName, context);
} catch (JAXBException ex) {
LOG.fine("Error creating a JAXBContext using ObjectFactory
: "
+ ex.getMessage());
return null;
}
}
return context;
}
}
{code}
It appears that something is holding on to the synchronized lock on
packageContexts and thus calls just block. Any help on this would be
appreciated.
We are just trying to call a simple CXF service that uses JSR-311 annotated
