Those are bugs

6976265 OpenJDK: STROKE_CONTROL not supported

6967436: lines longer than 2^15 can fill window.
6967433: dashed lines broken when using scaling transforms.

They seem fine for OpenJDK 6, but unless there is an urgent need for the 
fixes, I'd prefer them going into the next build, b22, rather than the 
current one, b21.
