"The bounds of a task should it be relative to its swimlane?"

--------------------------------------------------------------
I eventually come to an unexpected behavior
when planning to import/export a BPMN2 file to/from the designer of drools-guvnor demo.
http://localhost:8080/drools-guvnor http://localhost:8080/drools-guvnor
Does anyone have any ideas on this issue?
If a swimlane is at (10,10) and its containing task (80,80) in a BPMN2 file,
then the web designer will display that task at (90,90) which is (10+80, 10+80), relative to the container lane.
However, by reading the specification of BPMN, I thought (80,80) would be correct.
* Rationale
The graphical diagram aspect of a process definition is serialized in the BPMN file using BPMN DI (BPMNShape etc.)
According to the Specification, The bounds of a BPMNShape are always relative to the origin point of its BPMNPlane.
As both swimlanes and tasks are depicted using BPMNShape,
the bounds of a task are't relative to the origin point of its container swimlane.
Instead should it just be relative to the origin point ofits owner plane, i.e. usually a process .
For instance, Figure 12.132 and Table 12.41 of the Specification
* Actual:
When I create an arbitrary BPMN file including a task within a lane and import it to drools-guvnor,
then the web designer displays my task relative to the lane.
This actual behavior is diffent from the expectation above.
* Note
I found a bug related to the issue above :
https://issues.jboss.org/browse/JBPM-3782 https://issues.jboss.org/browse/JBPM-3782
but it says node's x/y values in bpmn file are relative to Swimlane, which is different from my understanding.
