API setSecurityQuestions exception

Question

Hi Folks,
I am using the Identity Manager API to allow setting of security questions and changing of passwords. However I have found that the setSecurityQuestions() method in the Thor.API.tcUtilityFactory seems to be throwing odd exceptions when i supply an incorrect password.
For example in this method here i try to set the security questions for a user. Passing the correct username and password works fine. Passing the wrong password you would expect it to get a tcPasswordIncorrectException, but it gets a tcAPIException instead, with the isMessage being "none", not so usefull.
This sounds a wee bit like a bug to me, just wondered if anyone had came accross it?
public void setSecurityQuestions(String userID, String pwd, Map QAmap)throws Exception{
try {
Thor.API.tcUtilityFactory.tcUtilityFactory.setChallengeValuesForUser(connectionEnv, userID, pwd, QAmap);
} catch (tcNumberOfChallengesMismatchException ex) {           
throw new Exception(ex.isMessage);
} catch (tcInvalidQuestionException ex) {
throw new Exception(ex.isMessage);
} catch (tcUserAccountInvalidException ex) {
throw new Exception(ex.isMessage);
} catch (tcUserAccountDisabledException ex) {
throw new Exception(ex.isMessage);
} catch (tcPropertyNotFoundException ex) {
throw new Exception(ex.isMessage);
} catch (tcDuplicatePropertyException ex) {
throw new Exception(ex.isMessage);
} catch (tcInvalidLookupException ex) {
throw new Exception(ex.isMessage);
} catch (tcPasswordResetAttemptsExceededException ex) {
throw new Exception(ex.isMessage);
} catch (tcLoginAttemptsExceededException ex) {
throw new Exception(ex.isMessage);
} catch (tcPasswordIncorrectException ex) {
throw new Exception(ex.isMessage);
}catch (tcAPIException ex) {
throw new Exception(ex.isMessage);
}

...just incase anyone wonders, there seems to be no information anywhere in the exception which comes back on a wrong password.
ex.isMessage = "(none)"
ex.getMessage() = "(none)"
ex.getErrorCode() = null
ex.getAction() = null
