[opencms-dev] Allowed chars for passwords?

[Anatol]

Hi All!

Could it be, that some chars are not allowed for using in passwords? I 
changed my password in opencms and one char was an "+". After relogin, I 
got an error (Tomcat: nullpointer exception if I remember it right) :-( 
Good to have an Admin-User ;-) I tested it again and again: If I used a 
password without a "+" char, the login was correct, but if I used a "+" 
i got the error.
Are some chars not for use in passwords or is it a bug?

Greetings
