JDK 1.4 class format problems?
Tim Tyler
The applet at:
http://texturegarden.com/preview/
...produces no animated textures under JDK 1.4.
There are no errors - just no display.
Running as an application offline produces here:
C:\Documents\Java\texturegarden>java TextureGarden

Exception in thread "main" java.lang.ClassFormatError: Texture (Invalid

This program works without issue on other JVMs.
There seem to be two separate problems. I don't know what the first
failure is - but I speculate that the second may be caused by more
stringent class verification - something that seems likely to cause
program failures elsewhere.
Reports relating to whether this applet fails on other people's machines
(under v.1.4) would be warmly welcomed.

It turns out this was also a problem with Sun's 1.3.1 JVM - though the
program worked OK under other JVMs.
I've recompiled everything - and it has started working again...
