+ Building on a more recent JVM than the code will run on. Java class file
+ format has changed a number of times over the years, and code compiled
with
+ a modern JVM may fail to load in an older JVM with the error message
+ "invalid class file format" unless the code is compiled with appropriate
+ options set. If you are using Maven, then ensure that project.properties
+ has maven.compile.target set to the minimum JVM version your binary is
+ intented to support. If you are using Ant, then ensure that the javac
task
+ has xml attribute "target" is set to the appropriate JVM version.
