It seems that Sun doesn’t care much about getting bugs fixed in Java.

This bug for example causes rendering artifacts in Apache Batik, and is very visible with many SVG files. It causes circles to be rendered as approximated diamonds. It has been reported 9 years ago (the first time, there duplicates).

I understand that there are both more important bugs, and that one must avoid introducing new bugs when fixing bugs. But there should be little dependencies on a broken circle rendering routine, so please just fix this cosmetic bug, too. One of the reports is even staged “Fix understood” …

A more important issue with Sun Java (known since 2005) is this bug, which effectively breaks Java IPv4 networking on Debian unstable now (which recently changed the IPv6-to-IPv4 fallback behaviour). So far, Sun has rated this as “request for enhancement”. WTF?

Sure, you can work around the bug easily - change /etc/sysctl.d/bindv6only.conf to use the value of 0 instead to re-enable IPv4 fallback - but after all, IPv4 networking is pretty much an essential Java feature.
