[PJUG Javamail] javac -version in MANIFEST.MF ?

[Send Here]

Don't know if anyone replied yet (I'm receiving a digest), but I just realized that ant <jar> already added this header, which is mostly what I had wanted:

Created-By: 1.6.0_03-b05 (Sun Microsystems Inc.)


"java -version" returns "build 1.6.0_03-b05", and "javac -version" returns "1.6.0_07", but this is close enough.

Is there a standard manifest header or standard practice for publishing the "javac -version" used in compiling the .class files inside a JAR?  "Specification-Version" seems like an ideal header to show the version of your application, but then you'd need a second header to record the version of javac used to compile.

I'm working in several environments right now with multiple javac versions and it's my understanding that you cannot successfully run one jvm on a combination of class files built with different major versions of the compiler.
