Wilfdly 10 clustering - IllegalArgumentException: Illegal base64 character 2b

mpicque Feb 23, 2016 9:58 AM

We upgraded our wildfly production platform from 7.1 to 10.0.0.Final.

We have a cluster with 4 nodes with default session replication configuration on JDK 1.8.0_72.

Since then we experience these exceptions below :

It seems to occurs during session replication.

Any ideas on the cause and the consequences ?

pferraro Feb 24, 2016 4:05 PM (in response to mpicque)

I see the problem...
AS7 (via JBoss Web) allowed for the '+' character (i.e. 2b) in its session ID:
http://anonsvn.jboss.org/repos/jbossweb/branches/7.0.x/java/org/apache/catalina/session/ManagerBase.java
WildFly (via Undertow) does not:
undertow/SecureRandomSessionIdGenerator.java at 1.3.x · undertow-io/undertow · GitHub

The problem is, your users will likely have a cookie containing the old session ID, which contains a character that the distributed session manager does not expect.
However, WildFly should not break like this if a session is requested using a session ID with an invalid character, and should instead respond as if the session was not found. See:
[WFLY-6278] Requesting a session with an unexpected character causes request to fail - JBoss Issue Tracker

Thank you for the quick response!

So do we have to wait for the patch or we have another solution in the meantime?

We have also another error "illegal base64 character" :

4. Re: Wilfdly 10 clustering - IllegalArgumentException: Illegal base64 character 2b

That exception is due to the same problem - and is addressed by my fix. I recommend that you checkout the 10.0.0.Final release from git, cherry-pick my commit, and rebuild.
Until this is fixed, any client browser that contains a reference to an old JSESSIONID (from AS 7.1) containing the "+" character will throw an exception when they try to access your application on WF10. At the moment, the only workaround is for these users to remove the corresponding cookie associated with your site, or wait for it to expire.

Hi everybody,

I had the same problem and solved it replacing all white spaces by '+' (plus sign) .

My client (Restful) sends an encoded base64 image to my server but in decode method threw an exception.

My environment:
Java 8,
Wildfly 10.1.0.Final (updated from WildFly 10.0.0.Final)
Jackson 2.5.4
