Anyone had a look at http://javolution.org/ ? It looks very promising! Stefan

I intended to implement this as a specialized ModuleDescriptorProvider which can save and load a ModuleDescriptor object to / from a file. My first attempt at this was to just have all the affected classes (*Descriptor, *Rule classes, etc.) implement java.io.Serializable and then serialize the ModuleDescriptor object to a file using standard Java object serialization. Alas this didn't result in any significant performance gain. By implementing java.io.Externalizable I am sure some performance could be gained. But at the cost of some complexity. Also I'm wondering how much performance there is to gain by doing this. I was wondering if any of you had any other ideas on how to approach this. E.g. use Javassist? Further, once we find a feasible caching technique I think we should also deliver this serialized form inside the jar files. E.g. a META-INF/hivemodule.xml.ser file. What do you think about that?
