bpm-console.war failed to start after restarting jbpm

[mberta]

My testing environment:

jbpm-6.4.0.Final on CentOS 7 with Oracle JDK 7

jbpm is configured to use mysql db

jbpm is started with ant start.demo.noeclipse

After playing with jbpm-console, creating organization units, repositories, projects and jbpm processes, jbpm was stopped and now I'm getting to following error on startup:

jbpm-6.4.0.Final/wildfly-8.2.1.Final/standalone/deployments/jbpm-console.war.failed: http://pastebin.com/anDfzNb8

jbpm-6.4.0.Final/wildfly-8.2.1.Final/standalone/log/server.log: http://pastebin.com/VJdBebun

Any suggestion ?
