linux emulation fix for jdk1.2.2 problems

Post by John Rochest » Thu, 03 Feb 2000 04:00:00



I have patches to the linux module in 3.4-STABLE that fix socket
and tty bugs that affect the blackdown jdk1.2.2.  In particular,
Apache JServ works.  If anybody wants them, let me know.

1. JDK1.2.2 vs JDK1.1.7 on COL 2.3 -- some comments

I'm running a Toshiba Satellite 2595CDS -400Mhz 64Mbyte,4 gig with Windows
98/Caldera Systems 2.3 and a 2.2.12 kernel. Installed on this I have "Sun's"
JDK1.2.2 port and Blackdown's JDK1.1.7 port. On the Windows side I also have
JDK 1.2.2 and the Beta JDK 1.3

I just upgraded from Caldera Systems 1.3 and a 2.0.35 kernel. On this I had
Blackdown's JDK1.1.7 port

I recently had a Samsun laptop 75Mhz ,24Mbte, 500Mbyte that had Windows 95 /
Caldera Systems 1.3

Upstairs I'm running an ACER 125Mhz, 16Mbyte that has Windows 95/Caldera
Systems 1.3 with the JDK1.1.7 port.

On each machine I have the same Java app that I developed starting with the
first Java release and upgraded it through subsequent releases until now
it's totally Swing.  On my Toshiba I can run the app with JDK1.17 and
JDK1.2.2 side by side.  On the Linux side the JDK1.2.2 takes 3 seconds to
draw a graph whereas JDK1.1.7 draws it in a flash.

Is there anyone else out there that is seeing this?
It's not Linux. It's not KDE.  It's Suns JDK1.2.2.  The question is why.  I
haven't touched it. It's configured as it was downloaded. The JDK1.2.2 on
the Windows side does just fine.  No it's not the 1.3 swap problem that's
been fixed.
The only abnormal thing about the execution is the system's inability to
resolve a lot of fonts when the app comes up, but I don't see how that would
cause the slowness in the graphing.
Going into Graphics2D doesn't help. I took it out to see if it sped up.
Any suggestions out there.  How about the font thing.  How do I resolve
that.

Thanks,

Jim
