#34 Error making ticket with special char & in password

[Anonymous]

I use JML in an Android app. Whenever someone with the special char & in his password (e.g. password: password&) tries to login, the following exception gets thrown:

net.sf.jml.exception.LoginException: Login Failed, error making ticket!
