FULL PRODUCT VERSION :
java version "1.6.0-rc"


A DESCRIPTION OF THE PROBLEM :
If the TransferHandler's exportAsDrag method is overriden so that it does not invoke the super implementation the autoscroller deactivation/activation mechanism in DragHandler will not be invoked. The DragHandler is only created in exportAsDrag and it appears to have sole responsibility to deactivate/activate autoscrolling when a drag is enabled.

Some options:
1. Document that its the responsibility of this method to activate/deactivate autoscrolling.
2. Document that the user should always invoke the implementation if overriden
3. Design an alternative mechanism that will always ensure autoscroll deactivation/activation when draggin is occuring



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Read code, see that this is the only place where the mechanism is instantiated and plugged in.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
that it will not be breakable
ACTUAL -
it can be broken

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
read the source for TransferHandler, see that the mechanism is used in only one place.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
1. Always invoke the super method.
2. Deactivate/Activate autoscrolling on your own
