What version of JVM do JRuby 1.7.3 use?

I’m reading Google AppEngine Java instructions. They say it is built now
on JVM 7. But I cannot find any info about JVM on JRuby site. Is it
important to know the version of JVM JRuby uses if I want to upload my
JRuby app on GAE?

For now found this article
http://blog.jruby.org/2011/12/getting_started_with_jruby_and_java_7/

Once you’ve got JRuby installed and in PATH (via whatever mechanism)
and Java 7 installed and in PATH (via whatever mechanism),
you’re ready to test it out!

So is this enough to know to use JVM 7 with JRuby 1.7.3?

It works with Java 6 as well…

JRuby runs fine on Java 7. If that is the Java available on GAE, I
think it should work well.
