IdentityLoginModule.java, impossibile to avoid IllegalArgume

[sunbeststar]

Hi all.
I develop the web-console for jbpm server and I tried to use IdentityManagement component for it. When I access IdenityLoginModule, and call a login() method, I get an IllegalArgumentException, which I cannot avoid in anyhow.
Here is the listing of login method:

public boolean login() throws LoginException {

// get userName and password
NameCallback nameCallback = new NameCallback(null);
PasswordCallback passwordCallback = new PasswordCallback("pass",false);
try {
callbackHandler.handle(new Callback[]{nameCallback, passwordCallback});
} catch (Exception e) {
e.printStackTrace();
throw new LoginException("callback failed");
}
.... .... ....
}


In the first string there is a constructor of NameCallback, which is:

public NameCallback(String prompt) {
if (prompt == null || prompt.length() == 0)
throw new IllegalArgumentException();
this.prompt = prompt;
}


As soon as NameCallback constructor is invoked with a null argument, the code throw IllegalArgumentException immediately, and I cannot do nothing..

Can you explain how is it possible, if this class was tested or if I do something wrong?..
I use JBPM 3.2.2, jbpm-identity.jar-3.2.2 e JDK 1.6.0.

Thanks a lot!

e.printStackTrace();
