securementActions - UserTokenAction (dissapearing username)

Hi All,

1. There is a problem with dissapearing username
a) username is set on "" (empty string) in line 39 of UsernameTokenAction class,
b) becouse in line 102 of Wss4jHandler i have not securementCallbackHandler,
c) and else body is run (line 130 of Wss4jHandler), with:
callback = new WSPasswordCallback("", WSPasswordCallback.UNKNOWN);

Is there any reason to set ID with empty string instead of to use passed to method username?

2. Last changes in wss4j-1.5.4 has broken our integration tests To find a problem we spent much
time, becouse no one imagine that is passible to change major things without upgrading version of library

HTH
