Honestly, it's pretty tricky to see anything in these logs (they're quite extensive to say the least).
Can you pinpoint exactly why it is blocking.

Hello Hermes,

it's indeed pretty tricky to see anything in the log. You should consider that WebSphere does not like the long running Job Executor Thread. In Java EE environments you are discouraged to create new threads on your own - but that's exactly what's done in the default Activiti JobExecutor implementation.

Have a look at this thread (http://forums.activiti.org/comment/9783) and consider the implementation Heiko (bardioc) posted:
