I am sorry to be a pest, but I am under-the-gun to get this resolved. I have followed the instructions for installing GATK2 on my cloud VM. After doing that I discovered that the version of java running on the VM was v1.6.x and GATK2 required v1.7.0x. I removed version 6 and installed version 7, uninstalled GATK2 and reinstalled it and reset all of the settings that may have reverted with the uninstalls/reinstalls. Now when I run Unified Genotyper I get the following error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/broadinstitute/gatk/engine/CommandLineGATK : Unsupported major.minor version 51.0

Could not find the main class: org.broadinstitute.gatk.engine.CommandLineGATK. Program will exit.

Researching this I found a post at http://gatkforums.broadinstitute.org/discussion/3378/gatk2-error-when-i-tested-it-after-installing that refers to upgrading java as the solution. However, that did not fix the issue. In addition I copied the jar file to a temp directory and unzipped it to examine the MANAFEST.MF file for versioning issues. This is what I found:

Manifest-Version: 1.0

Build-Jdk: 1.7.0_51

Built-By: gsa-engineering

Created-By: Apache Maven

Main-Class: org.broadinstitute.gatk.engine.CommandLineGATK

Archiver-Version: Plexus Archiver

This tells me that there is something else causing the problem. Does anyone have an idea where to look now?
