Hmm, I'm not expert in swing. Actually I'm just playing with swing-0.7
(very old distribution, right?). Mostly running examples and trying to
modify them. But today I download swing-1.0.3 and found following feature.
Image output speed during image loading (in SwingSet example, ScrollePane
component) is *extremely* slow even when I using TYA JIT compiler. After
image had decoded everything works fine with usual speed. So, I'm a bit
confused with this "feature" too.
I'm using jdk-sbb-1.1.6-2.1.2glibc.rpm on Red Hat 5.1 system,
glibc-2.0.7-19.
