I have filled a bug report against Mageia Linux:

This bug is reproducible only with the XRender pipeline. Best regards.

This bug is only reproducible under Mageia Linux. I will try to fix it by myself as nobody feels concerned.

Actually, the problem comes from the drawing of the first point rather than the end cap. Best regards.

I try to draw a diagonal cross and I get a different result with the same code under Microsoft Windows with Oracle Java 1.7 update 60 (expected result) and under Mageia Linux 4 with OpenJDK 1.7 update 60 (wrong result).

Please find enclosed my small test (50 lines of code) and an image showing the extra pixels on the diagonal cross.

I tried to disable the Java2D pipeline based on XRender and the anti-aliasing (by using the rendering hint) but it didn't help.

Let me know whether I should fill a bug report.

Best regards.
