    Description

      The javac compiler has long supported compiling to different source levels. However, as documented in the javac man page and written about elsewhere (http://blogs.sun.com/darcy/entry/how_to_cross_compile_for), setting the source level alone is not sufficient to generate code suitable to run on an earlier version of the platform. The bootclasspath needs to be set to the earlier platform version too.

      To help catch this situation, javac could warn if an earlier -source is used and bootclasspath is *not* set explicitly set.
