I see, it makes sense now. Could be useful for network usage.
FYI, from what I could observed, when the plugin loading system is scanning the URL from the classpath there is a big overhead when there are many files, not many classes. Exemple : All the Sextante algorithm (more than a hundred) classes are dynamically loaded (using forName() and newInstance()) in a few seconds (2 or 3 seconds max) When FillPattern images was added, each single forname(classname) and class.newInstance() was 4x or 5x slower ! which rapidly made the total loading time grow to 20 s.
