When deploying webapp - by deploying jbpm-war - in order to launch the CommandThreadExecutor, got this error appearing :
11:23:38,491 INFO [STDOUT] command 'null' threw exception. rolling back transaction
11:23:38,501 ERROR [CommandExecutorThread] java.lang.NullPointerException
This error message appears every few seconds when the "executeCommand()" method is called.
DB's table "MESSAGE" is empty.
Besides this, CommandThreadExecutor is working properly.
Thanks for your help.
