Description

When I try to use CompositeActionMapper on Oracle JRE 1.7.0, the ContainerImpl tries to first inject the actionMappers using CompositeActionMapper.setActionMappers(String list), before the container is injected in setContainer(Container container). This leads to a NullPointerException.

This did not happen on Oracle JRE 1.6.0.

The apparent cause is that in com.opensymphony.xwork2.inject.ContainerImpl, line 90, the method injectors are created in the order in which the methods are returned by Class.getDeclaredMethods(), which is undefined according to the documentation.
