Description Nick Cross 2013-12-02 09:45:25 UTC 
BPELConsole depends on Errai 1.1. This depends on org.reflections reflections-0.9.5-RC2_jboss-SP1.jar which pulls in Google Collections 1.0. This appears to conflict with com.google.guava guava-13.0.1-redhat-1.jar (from EAP). 

Guava superceded Google Collections (http://code.google.com/p/google-collections). Note that the 0.9.5 version of org.reflections from Maven central does not have this collections dependency ( http://code.google.com/p/reflections  /  
http://central.maven.org/maven2/org/reflections/reflections/0.9.5/reflections-0.9.5.pom  ) : it has started to move to guava as well.

The error message we get on server startup is 

09:39:44,945 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/bpel-console]] (ServerService Thread Pool -- 54) JBWEB000289: Servlet ErraiServlet threw load() exception: java.lang.NoSuchMethodError: com.google.common.collect.ImmutableSet.of([Ljava/lang/Object;)Lcom/google/common/collect/ImmutableSet;

      BZ1036559 / BZ1038267 Fix for BPMConsole GoogleCollections/Guava clash
    The real bug is in the Drools/jBPM modules, so we'll fix it there instead.
