If your action is located with the help of a prefix rather than the whole class name(the PrefixActionFactoryProxy does this) then it is very difficult to track down exceptions thrown in the constructor or during class initialisation. This is because the PrefixActionFactoryProxy just swallows the exception and tries to find an action with another prefix, so you will never know what went wrong. I solved this by changing the JavaActionFactory to throw InstantiationException if the newInstance called failed. The prefix factory then catches that exception separately and re-throws it rather than looking for another action. This takes care of constructor exceptions at least.
