Re: Having multiple versions of CXF deployed in the same OSGi container

[Daniel Kulp]

I can almost guarantee that having two versions of CXF deployed into the same 
OSGi container won’t work.  The loading of the Bus extensions from the various 
bundles does not currently take into account the CXF version they are tied to.

Re: CXF v2.7.14 JAXB blocked threads and degraded performance

[Daniel Kulp]

This stack trace looks like it’s during creating a client proxy.  Is that 
something you do a lot?  If so, you really should either pool the proxies or 
use them in some other thread safe manner to avoid creating them all the time.  
Creating them is expensive and involves several locks.In this particular 
case, it’s creating a JAXB context.   In theory, the context cache can hold 
onto and share the JAXB contexts between multiple client proxies, but if the 
proxies are discarded and not held onto, the cache would clear as well and 
contexts would need to be re-created.

CXF v2.7.14 JAXB blocked threads and degraded performance

[venkatesham nalla]

degraded performance with CXF v2.7.14 with bunch of threads in BLOCKED state  
waiting to lock <0x000685890f28> (a 
com.sun.xml.bind.v2.runtime.reflect.opt.Injector) with the following 
stacktrace, teh thread that is holding the lock is in Runnable state. Is this a 
bug or how do get around this performance issue?
