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

Post by Jim » Thu, 16 Dec 1999 04:00:00



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

 
 
 

1. Native threads with Java JDK1.1.7 on SuSE Linux

I am having some trouble running my Java app using native threads. I get the
error message:

error in loading shared libraries
undefined symbol: Java_java_net_PlainSocketImpl_initProto_stub

When I change threads to green, everything works fine. I am using the Java
shipped with SuSE - I have no idea whose it is, but is is 1.1.7.

Has anyone seen this problem?

I am running SuSE Linux 6.1, which corresponds to kernel 2.2.5. FWIW - I
have also turned on SMP in the kernel.

Thanks

Jim
