 * options which specify the version are not passed to the exec'd version,

 * because that jre may be an older version which wouldn't recognize them.

 * This environment variable is known to this (and later) version and serves

 * to suppress the version selection code.  This is not only for efficiency,

 * but also for correctness, since any command line options have been

 * removed which would cause any value found in the manifest to be used.

 * This would be incorrect because the command line options are defined

 * to take precedence.

 *

 * The value associated with this environment variable is the MainClass

 * name from within the executable jar file (if any). This is strictly a

 * performance enhancement to avoid re-reading the jar file manifest.
