Hi Clemens,

Looks fine should solve the problem. Perhaps it would have been nice to
calculate the interpolation with the clip but then you'd need to pay
attention to whether it was a complex clip or a simple rectangular one
and it may be better to do the delegation that you are doing now ...

Hi,

Please take a look at the patch for bug 7150134, located at
http://cr.openjdk.java.net/~ceisserer/7150134/

The problem was caused by a fast-path in drawLine() which didn't take
clipping into account, therefor huge lines that would have been
clipped away caused OOMs in xrender's bresenham code. Because the
fast-path provides nice speedups (e.g. 300% for 20px horizontal lines
measured with J2DBench) I don't want to sacrifice it entirely.

This fix only takes the fast-path in case the line is completly
un-clipped, otherwise it lets generic Java2D code handle it:
