It's unbelievable and unprofessional that a software development-oriented site doesn't allow a password change. Furthermore, there isn't even a good place to register this as a problem.
I tried to change your password in our staging environment which is almost 1:1 to production and everything worked OK.
Do you still experience this issue?
If yes could you please create a jira ticket - JBoss Issue Tracker as Jaikiran mentioned?
