[Bug swing/27835] New: ArrayIndexOutOfBoundsException in CarioGraphics2D.fillRect

[hendrich at informatik dot uni-hamburg dot de]

I just tested my image-viewer application with classpath cvs 2006.05.31. Apart
from the repaint issue (#27833) and the JSplitPane scrolling problems, I get
the following exception:


java.lang.ArrayIndexOutOfBoundsException: While writing data elements, x=120,
y=
119, width=120, height=120, scanlineStride=120, offset=14400,
data.getSize()=144
00, data.getOffset()=0: java.lang.ArrayIndexOutOfBoundsException: 14400

Looks like an off-by-one error in CairoGraphics2D or BufferedImageGraphics,
but I don't have a simple testcase. Perhaps the data reported by the exception
is enough to hunt the bug?

BTW, previous versions of classpath would just die somewhere when trying to
create the thumbnail images (jamvm deadlocked and I never got useful
stacktraces) , so the above exception is a clear improvement.

Best, Norman
