Try "rpm -ql java-1.7.0-openjdk-src | less"

The default of "JAVA_HOME", now, that's different, because you can
reasonably safely install multiple versions of java with multiple
relevant "JAVA_HOME" directories and pick which set to use. The
defaults wend a twisty path through "/usr/bin/java" which is symlinked
to "/etc/alternatives/java", which is symlinked to
"/usr/lib/jvm/jre-[version]/bin/java"

If you need to muck with JAVA_HOME to pick alternative versions, use
/usr/lib/jvm/java-[version].[arch]. Otherwise, stop trying to outsmart
it and simply use the "/usr/bin/java" or "/usr/bin/jre" symlinks as
needed.
