Change subject: core: Don't use commons collections clone method ...................................................................... core: Don't use commons collections clone method The commons collections package provides a mechanism to clone an object doing serialization and then deserialization. Unfortunatelly the implementation uses its own class loader (the class loader that loaded commons collections itself) to load the class of the serialized object. This means that the deserialization will fail if commons collections happens to use be loaded by a class loader that doesn't have access to the class being cloned. This is what happens if we try to use a JBoss module instead of dropping commons-collections in the lib directory of the ear. This patch implements the clone method so that it uses the context class loader if possible, this solves the issue with separate class loaders.
