After a very similar log appears, the designer stop working and the page has to be reloaded 11:34:31,024 INFO [stdout] (http-localhost/127.0.0.1:8080-6) 205864 [http-localhost/127.0.0.1:8080-6] ERROR org.jbpm.designer.web.server.DictionaryServlet - In my case, the error seems to be related with: https://community.jboss.org/thread/232335?start=0&tstart=0 I am using 6.0.0.CR2 under linux (64 bits).
This has been changed to an info message that is more clear: INFO [org.jbpm.designer.web.server.DictionaryServlet] (http--127.0.0.1-8080-1) Unable to find existing dictionary information. Fix in designer master and 6.0.x branches
