Why Bother – Root already exists?
	• Philosophical Reasons – If we are committing a large amount of HEP data to Root, it is good to know it can be read back even without Root • Java package is currently only 5000 lines of code. • We need it for JAS, Wired etc. – Calling C++, Fortran code + interface to Java is bigger overhead (c.f. Paw, StdHEP). • Returns all the problems we got away from by using Java – Porting issues (E.g. MacOS) – Crashes • Java Applets etc. – Security considerations may not allow native code
