The wrapped exception is:
java.lang.UnsupportedClassVersionError

This leads me to believe the JRE/JDK you're running doesn't
support Green. Green requires 1.5. Ensure that your
workspace and JRE settings (under Window > Preferences >
Java > Compiler, Window > Preferences > Java > Installed
JREs) are set to use the appropriate version.

The problem was the JRE version under Window > Preferences >
