Create a VERSION file in the JDK that contains the FULL_VERSION.

Currently the only way to find out what version a JDK is, is to run 'java -version', but if the JDK is for a different platform or you can't run 'java -version' you can't find out what version it is.

The JPRT system would like to be able to know what version a JDK is, in a platform independent way and easily without using 'java -version'.

See suggested fix: Add a VERSION file inside the jdk and jdk/jre directories that contains the full jdk version.
