Also, getRetractLocation() returns the incorrect location based on the opposite direction. No doubt this encouraged the view point that the direction was incorrect as well. But it looks like that method was deprecated at some point. Still, it caused some problems with plugins using this event.

Ok so basically:
1) Server never used to fire a retract event for sticky pistons, only an extend event which moved the blocks backwards (not really logical but whatever).
2) Server now does fire a retract event for sticky pistons as of 1.8
3) The documentation for "piston event" says ""Return the direction in which the piston will operate."
4) Based on my interpretation of this documentation, which hasn't changed, the direction is the direction in which the piston moves the blocks. So for a piston facing North, it will Extend North and Retract south.

If no one has any issues with this, I would like to amend the javadoc and then consider this issue solved.

The founction's description in JavaDoc is "Return the direction in which the piston will operate." and returned the direction of the piston. when BlockPistonRetractEvent called by the normal piston,the relative block in that direction is the PISTON_EXTENSION.

Works as indented. Direction is direction the blocks are moved.
The blocks are moved to the left. So the relative block in that direction is the TNT block.
