When attempting to use the RememberMe component in auto-login mode I discovered a bug in the cookie handling of this component.
My system is:
JBoss 5.1.0 GA Seam 2.1.2
When attempting to log using an auth token I was encountering repeated failures - the token was simply not being found in the database. After some investigation I discovered that the problem was that the value parameter passed into the query was truncated by one character - the last character was cut off.
I tracked the problem further back, and discovered that the truncated value originated in JBoss' Tomcat. The cookie value being passed in was missing the last two '=' characters.
Some Google searching revealed that this was deliberate - Tomcat 6 in the JBoss 5.1.0 GA configuration enforces strict character rules in the cookie value, which excludes '='.
I'm not sure if Tomcat 6 is 'right' or not, but I do know that either way, this is a trivial issue to address on the Seam side.
All one has to do is replace the '=' from the Base64 encoded token value with another allowed character (say 'g' or '-') before placing it in a cookie, and reverse the process when reading a cookie.
What steps are required to file this as a bug/submit a patch? I've reviewed the code and the change is straightforward.
