Class FutureArrays

java.lang.Object
org.apache.lucene.util.FutureArrays
public final class FutureArrays extends Object
Additional methods from Java 9's java.util.Arrays.

This class will be removed when Java 9 is minimum requirement. Currently any bytecode is patched to use the Java 9 native classes through MR-JAR (Multi-Release JAR) mechanism. In Java 8 it will use THIS implementation. Because of patching, inside the Java source files we always refer to the Lucene implementations, but the final Lucene JAR files will use the native Java 9 class names when executed with Java 9.
