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

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:

In this thread http://forum.openkm.com/viewtopic.php?t=12414 there is a note saying that jdk 1.7 should be used for both OpenKM (tomcat) and for jBPM (workflow creation). Could you please tell if it is strict requirement or jdk 1.8 should also work?

Thank you in advance.

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/
