hamsterdancer [http://community.jboss.org/people/hamsterdancer] created the discussion "Console crashes on opening Process Overview (fresh jBPM5.2 installation)" To view the discussion, visit: http://community.jboss.org/message/642936#642936 -------------------------------------------------------------- Hi there, I've just downloaded and installed jBPM5.2 with the installer and started the demo. Then I log me in to the console ( http://localhost:8080/jbpm-console http://localhost:8080/jbpm-console) with krisv (or any other user name) and click Processes -> Process Overview. The console crashes with the following less helpful Exception. Maybe I forgot to configure something to configure. But I was relying on my experiences with jBPM5.0 and 5.1 where it was not needed to configure jBPM or the console in any way for the first start. Any good ideas or advices? Thanks :) Stacktrace: 18:24:27,443 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/gwt-console-server].[Resteasy]] (http-localhost-127.0.0.1-8080-6) Servlet.service() for servlet Resteasy threw exception: org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Could not initialize stateful knowledge session: org.apache.commons.codec.binary.Base64.encodeBase64String([B)Ljava/lang/String;
