popup after switching to Process overview
On EAP 6.1, I am able to close the first error popup and switch to Process overview. This happens then.
The problem is probably caused by using wrong version of protobuf library, see the following exception cause in the log: Caused by: java.lang.VerifyError: class org.drools.marshalling.impl.ProtobufMessages$RuleData overrides final method getUnknownFields.()Lcom/google/protobuf/UnknownFieldSet Exactly. As mentioned in Bug 1000385 (included for that roll up list) all protobuf jars must be updated to version 2.5.0. The protobuf libraries version is now correct, but it seems that protobuf classes have not been regenerated for jBPM engine:
Caused by: java.lang.UnsupportedOperationException: This is supposed to be overridden by subclasses.
[java] at com.google.protobuf.GeneratedMessage.getUnknownFields(GeneratedMessage.java:180) ~[protobuf-java-2.5.0.jar:na]
(see attachement for full stack trace)
It seems the following commit did not make it into the patch:
https://github.com/droolsjbpm/jbpm/commit/9b08e628d0fb9a45aaebbdc84e5961163aa70203
however, it is in the 5.3.x branch - it should probably be cherry-picked into 5.2.x first.

Exception when serializing a jBPM process instance
It seems the files were regenerated incorrectly on the 5.3.x instead of the 5.2.x branch. The files have been regenerated for 5.2.x now. http://github.com/droolsjbpm/jbpm/commit/2ae56b254 This product has been discontinued or is no longer tracked in Red Hat Bugzilla. |
