    NPE if using Infinispan without log4j.properties

    Chris Lowe Apprentice

      Hello,

       

      I'm just starting to kick the tyres with Infinispan (4.0.0.FINAL) and while doing so, I attempted to launch some code without having specified a log4j.properties which resulted in the following NPE:

      Just thought I'd let you know.  Making a log4j.properties config available in my classpath with a level above trace works around the issue.

       

      Cheers,

          Ahh - I know what's at play here. I had log4j.1.2.11 in my classpath rather than 1.2.15.

           

          The earlier version of log4j causes all sorts of problems.  In case anyone else goes down this path then the next error I got was with JGroups failing to start:

          The solution is to get log4j.1.2.15 and make sure this is version that appears first in your CP.

           

          Cheers,

            The same problem here, however upgrading to log4j 1.2.15 does not solve the problem. In general, for trace level of logging I'm getting NPE.

              Galder Zamarreño Master

              I can't see any NPE in the stacktrace you posted, but I suspect this NPE might be this: https://jira.jboss.org/jira/browse/ISPN-355

               

              Can you verify?

                Chris Lowe Apprentice

                In Eclipse, I also had to make sure that log4j.1.2.15 appeared first in my classpath - some other libraries used by my project had their own version of log4j defined.

                 

                Also, at runtime I was accessing Infinispan from a servlet so I had to manually remove an old log4j jar from my WEB-INF/lib and replace with the new version.

                 

                Cheers,

                  Hi Galder,

                   

                  The exception is wrapped a few times before being dumped to log.  At the bottom of the stack trace posted in the first entry there is the following:

                      The issue has been fixed in both trunk (http://anonsvn.jboss.org/repos/infinispan/trunk/) and a 4.0.x branch (http://anonsvn.jboss.org/repos/infinispan/branches/4.0.x/) we've created last week. So, if you really need the fix, simply export or check out one of them two and run:

                       

                      mvn -Dmaven.test.skip.exec=true install -P distribution
