private static boolean isJava6 ( ) { return isVersionBelow ( "java.class.version" , 51.0 ) ; }
are we running on a java 6 jre ( i . e . , is " java . class . version " < " 51 . 0 " ) ? note : here , we rely on the fact that you couldn ' t run streamsupport on 49 . 0 or lower anyways given that it is compiled for 50 . 0 .
