Yes, Ant acquires the main compiler class by reflection. See
org.apache.tools.ant.taskdefs.Javac13 if you're interested.

It's whatever JDK is being used to invoke Ant. The easiest way to
determine that is by running 'ant -verbose', it will be third line of
output. Depending on how you invoke ant, it might not be what is in
your PATH or JAVA_HOME. E.g. if you install Apple's Java developer
tools on Mac OS X, then running 'ant' in the shell invokes whatever is
the current base JDK level for Mac OS X, and is not what is in your
PATH or even in JAVA_HOME.
