> I encountered this bug when I was developping an application with jboss seam. At some point there was a Actor with no group ids. The processInstanceList component will invoke the getGroupTaskList(List actorIds)  with a List with 0 entries. 
> So we end up in org.jbpm.db.TaskMgmtSession.findPooledTaskInstances(actorIds) with the same List ( with 0 entries)
> I get this Exception:
> 10:43:42,265 ERROR [TaskMgmtSession] org.hibernate.hql.ast.QuerySyntaxException: unexpected end of s
> ubtree [
>       select distinct ti
>       from org.jbpm.taskmgmt.exe.PooledActor pooledActor
>            join pooledActor.taskInstances ti
>       where pooledActor.actorId in (  )
>         and ti.actorId is null
>         and ti.isSuspended != true
>         and ti.isOpen = true
