---------------------------------

             Summary: CompositeActionMapper actionMappers injected before 
container, leading to NPE on Oracle JRE 1.7.x
                 Key: WW-3994
                 URL: https://issues.apache.org/jira/browse/WW-3994
             Project: Struts 2
          Issue Type: Bug
    Affects Versions: 2.3.8
         Environment: Oracle JRE 1.7.0_17, Struts 2.3.8, Tomcat 7.0.12
            Reporter: Daniel Baldes


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.
