Jon,
I have experienced this problem when I create a jar file with eclipse or the java jar tool on a windows machine and then try to use it on the mac machine. The only workaround I have found is to recompile the jar on a mac. Then it can be used on both windows and mac. I would be very interested to hear a more complete solution to this problem.

Subject: Plugin problem on Macs
Hi,
I received the following email from someone using a plugin I wrote. Can anyone help me figure out the cause of the problem?
Jon
Working perfectly on Win XP SP2 on a Dell computer but doesn't working on Mac PPC.
Here is the two apple machine i use to test the plugin with ImageJ:
Apple G4 2x867 Mhz 1,5Gb Ram OS: Mac os x 10.3.9 Apple G5 2x2 Ghz 3 Gb Ram OS: Mac os x 10.3.9
On both machines i have the following error message in imageJ:
java.lang.UnsupportedClassVersionError: DStretch_ (Unsupported major.minor version 49.0)

I have the latest java update downloaded directly from "apple software updates"
Do i have the right Mac Os X? Do i need Tiger (10.4) or Leopard (10.5) ?
