> While profiling for performance issues on ServiceMix, we noticed a lot of
> time was spent waiting for the object lock to access MultiParentClassLoader's
> loadClass() method, especially when using things like JAXP. We managed to
> get significant improvements by adding a local cache to avoid the
> synchronized method invocation for previously loaded classes.
