    Resolution: Fixed

The current approach is acceptable, but we need to flag this issue for a more comprehensive solution in 2.0

> Currently WSS4J loads the BouncyCastle JCE (see WSSConfig.java). However, it uses the JCE Security class to then register the JCE in the java.security.Security registry. The problem is, that it uses the context classloader which might or might not be available for other parties. The JCE providers loaded via java.security.Secruity must be installed in the system classloader since it loads the JCE.
> JCE 1.4 and onwards provides a way to use an instance of a JCE provider supplied by the caller instead of the classes requesting one from the Security registry.
> For example to get a cypher, one can write
> Class clazz = myClassloader.loadClass("my.custom.JCEProvider");
> java.security.Provider myprov = (java.security.Provider) clazz.getInstance();
> javax.crypto.Cypher =  javax.crypto.Cypher.getInstance(myTransofrmation, myprov);
> instead of
> javax.crypto.Cypher =  javax.crypto.Cypher.getInstance(myTransofrmation);
> or
> javax.crypto.Cypher =  javax.crypto.Cypher.getInstance(myTransofrmation, "myprov");
> This way WSS4J will stay trully independent of any system-provider JCE providers.
> Same needs to be done for XML-Security library
