Hi guys, i recently had upgrade jbpm, but there is a problem on listing process
definitions.

I had this piece of code working:

Command cmd = new GetProcessDefinitionCommand(true);
| DataModel model = null;
|
| try {
| List l = (List)getEngine().execute(cmd);
| model = new ListDataModel(l);
| }
| catch (Exception ex) {
| ex.printStackTrace();
| }
| finally{
| return model;
| }
|

and after the update, there is no class GetProcessDefinitionCommand, only
GetProcessDefinitionsCommand. So I changed, and I get a lot of these exceptions
while listing:

17:11:50,468 WARN [AbstractGetObjectBaseCommand] exception while retrieving

I suppose there's some problem here and something missing on the release notes.
