What about this: 1) Each jar is deployed into it’s own classloader. 2) If the classloader for jar1 is unable to load a class, it delegates to its parent which can load classes from siblings to jar1.
The classloader hierarchy would be: bootstrap << system << application << (deploy jar)* where the application classloader manages the delegation to all deployed jars.
