Your VM is older than the compiler (a Java 1.5 compiler) which was used
to compile the class. Check if you don't have an old VM in your path by
accident.

I'm quite sure java 1.4 has 48.0 and java 1.5 has 49.0, so he must be
running something like 1.1, 1.2 or 1.3, while loading 1.4 classes.

Oh, it looks as if I have lost track of the class file formats
somewhere. For whatever reason I thought 1.4 had 46.0. Anyhow, I think
we agree that the OP runs a VM which is to old for his classes.

Because you compiled Your.java with Java 1.5 and you
port Your.class to other machine. That machine has installed
Java 1.4.x only.

So you need to compiled with -source option

javac -source 1.4 Your.java

Then you can run Your.class in both machines.

Or upgrade all your machines to Java 1.5

The solution is uninstall all your jdks, remove vestiges and start
over reinstalling is ascending order.
