The code is compiled using a newer version than the JVM you're running the code with. For instance, you compiled with a Java 6 compiler and are running with a Java 5.0 or before JVM.

Compile using the -target flag, specifying the JVM version you want to run your code with.


SCJP 1.4 - SCJP 6 - SCWCD 5 - OCEEJBD 6
