RFR 8183400: runtime/6981737/Test6981737.java fails with java.lang.RuntimeException: FAIL: Wrong value for java.version property, "9", expected to be of form: "[0-9]+[\\.[0-9]+]*\-.*"

Hi,

Please review this JDK-10 test bug fix.  The fix changes the test to 
call Runtime.Version.parse() to parse the "java.version" property value 
instead of using its own regular expression.

The fixed test was tested on Linux using "java.version" property values 
of "9", "9-ea", and "10-internal".

Thanks, Harold
