j_security_check works fine.... Sometimes.

[Guilherme Ceschiatti]

Hi!

My login system works fine sometimes, but there are times that it stops
working, without any change. I'm using EJBUserManager. It correctly add users
and groups in my database. The problem is that the login system
(j_security_check) do not work all the time. I realy don't know what makes it
work sometimes, and sometimes not. This is the exception when it doesn't work.
