Unable to start a simple workflow. java.lang.Error: Unresolved compilation problems

 #31402  by i.zemliansky
 
I am playing with OpenKM 6.3.0 with the latest OpenKM.war (revision 8185). Just decided to have some experiments with workflows. For this several software packages were installed:
1. C:\Users\izemlian>java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)
Available for both Jboss and OpenKM.
2. jBoss 8.0.0.GA
3. jBPM 3.3.1.GA
4. Windows 7 x64

A simple test workflow was created using this guide: http://wiki.openkm.com/index.php/Workflow_Guide. The workflow registered in OpenKM. When i start the workflow, i get an error, described in this topic: http://forum.openkm.com/viewtopic.php?t=12414

Here is information from catalina.log:

Better if you use jdk 1.7 and when us jump to 1.8 follow us. I see something strange with jboss 8.0.0 etc... my suggestion is download our development environment and use it. At least we'll be sure all is right http://sourceforge.net/projects/openkmportabledev/
