I downloaded the source today (11/02) and compiled with ant 1.8.2 and jdk 1.7. When I run: dist~/fseq/bin$ ./fseq -h I get Exception in thread "main" java.lang.UnsupportedClassVersionError: edu/duke/igsp/gkde/Main : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(Unknown Source) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$000(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) Could not find the main class: edu.duke.igsp.gkde.Main.

This error is caused by compiling with a different Java SDK than you execute with.
