I am trying to create a simple ArcObjects console app however when trying to initialize the ArcGIS licenses I always get the following error.
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
The error is encountered on the following line of code
ao.initialize(com.esri.arcgis.system.esriLicenseProductCode.esriLicenseProductCodeEngine);
I am using ArcObjects 9.3.1 and JRE 1.5.0 Update 10
I can successfully run the Scenario.Utility Object project located in the ArcGIS\java\samples\engine\ folder without error. This uses the exact same method to initialize the arcGIS license. I can also run my custom code if I put the class within the sample project. I have gone through the differences within the two projects and cannot find any differences between the Build Path or Complier.
Any help would be appreciated.

Are you using Eclipse? If so, you can make sure you are compiling your source code to the correct level by going to "Project Properties-->Java Compiler", then view your compliance settings. If you are using Java 1.5 at runtime, make sure your compliance settings in your IDE are set for 1.5.
Recompile, then redeploy. I hope this helps.
