It’s good to see that jdk.OracleVersion has been removed and use jdk.Version to obtain the fourth element of the version number.

This patch looks good in general.  Minor comment:

 273             current = parse(System.getProperty("java.version"));

System.getProperty will do a permission check and it needs to be called within a doPrivileged block.

 154  * @see  <a href="http://openjdk.java.net/jeps/223">JEP 223: New Version-String Scheme</a>

Does the javadoc have the essential information from this JEP?  Wonder if this @see is necessary.

Alan already comment on the “jdk” package that needs to find the proper module to export it (that’s a future RFE) and modules.xml should be updated.
