+ * The following environment variable is used to influence the behavior
+ * of the jre exec'd through the SelectVersion routine.  The command line
+ * 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.
