BaseConnectionManager2 does not propagate or log authentication exception cause

In org.jboss.resource.connectionmanager.BaseConnectionManager2.getSubject(), the following code handles authentication errors while obtaining a new database connection from the pool:

...
if (securityDomain.isValid(principal, credential, subject) == false)
throw new SecurityException("Invalid authentication attempt, principal=" + principal);
...

If there are errors during authentication, they are not logged or rethrown like it's done in AuthenticationInterceptor:

...
if (authenticationManager.isValid(principal, credential, subject) == false)
{
// Check for the security association exception
Exception ex = SecurityActions.getContextException();
if (ex != null)
throw ex;
...

In our case, we had a bug in our login-config for the security domain being used for the database connections. The real exception came from the LoginModule's initialize method, but the only message we got is a SecurityException with 'Invalid authentication attempt'.
