Your analysis seems to be logical as "major.minor version 51.0" matches with Java 1.7. I don't know why it was built with Java 1.7 but OpenJDK 1.6 became unusable a few weeks ago because of a major regression and some security changes were necessary for Java 1.7. I'm not sure supporting Java 1.6 is a good idea even though I understand that it can be annoying for end users.
