I can't change my password by the following form:
https://developer.jboss.org/change-password!input.jspa
It always returns "Please enter the correct current password." but my current one is definitely right because I was able to login with it.

My account is linked as a "Red Hat Employee". I guess the SSO integration has something wrong.

I found another user complaining. I'm not sure if he is related to SSO or not.
