 /**
- * Discovering the JDK_Version during initialization is tricky when the
- * running JDK is less than JDK6.  For JDK6 and greater, a "GetVersion"
- * function exists in libjava.so and we simply call it during the
- * 'initialize()' call to find the version.  For JDKs with version < 6, no
- * such call exists and we have to probe the JDK in order to determine
- * the exact version.  This probing cannot happen during late in
- * the VM initialization process so there's a period of time during
- * initialization when we don't know anything about the JDK version other than
- * that it less than version 6.  This is the "partially initialized" time,
- * when we can answer only certain version queries (such as, is the JDK
- * version greater than 5?  Answer: no).  Once the JDK probing occurs, we
- * know the version and are considered fully initialized.
+ * With the integration of the changes to handle the version string
+ * as defined by JEP-223, most of the code related to handle the version
+ * string prior to JDK 1.6 was removed (partial initialization)
