Description

Recently we've been profiling ODE by jProfiler and found thread synchronization block ODE and AXIS2 threads so much.

For example,in our 16 minutes test,calss sun.misc.URLClassPath blocked 342282 times and amounted to 30648 seconds. Class net.sf.saxon.om.NamePool has similar problem, maybe there are other candidates.

I think, if we resolve thread synchronization problem, ODE can perform much better.
