This could be a Linux problem but some on the Linux list speculated that
it might be an underlying Sun problem. If so, it seemed related to
Java2D. Whenever I try to run the SwingSet demo using the JDK 1.2
Preview from Blackdown, I get the following error:
java SwingSet
Error loading L&F: java.lang.IllegalArgumentException: Raster

My computer is an IBM 300PL with an S3Trio3D card using the 32 bpp
XFree86 FrameBuffer driver. I have been running my Swing applications
for a couple months using JDK1.1.7 and Swing 1.1 using this same
hardware. I have posted it as a Linux bug already. Does anyone have
any suggestions?
