I can respond to point 1. I have been using the Blackdown 1.3.0 FCS version
since it was released and have been quite happy with its stability. Notably
it works around some issues with the KDE 2.1 window manager (kwin) that I
have noticed seems to stump the Sun JDK. Although it's still not perfect in
its handling of screen placement of windows. The effect is quite noticable
with KDE and the Sun JDKs, including the latest 1.3.1 release candidate from
Sun. JOptionPane windows jump from being centered to being in the top left
corner of the screen and alternate. First one will pop up centered as it
should, then the next will be top left... and so on.
Apparently the KDE developers have put a workaround into KWin that will be
released later this year so that KDE responds to the JDK's query about what
kind of window manager it is by saying it's a CDE compatible window manager,
which the JDK (sun's or blackdown's) handle more closely to how it should.
Performance wise, I think both are close, I haven't noticed anything
strikingly obvious.
Other than the window placement, and window sizing issues, both JDKs work
quite well under Linux, which is nice compared to the dark years past where
only the kind folks from Blackdown, and before blackdown pulled the JDKs with
their own steam for so long. Now at least Sun is giving decent effort to it.
It can only get better from here.
