Change OutputStream.write(byte[],int,int) to use the same three parameter bounds checks used by InputStream.read(byte[],int,int) instead of the five checks currently used. This change is covered by the existing test jdk/java/io/OutputStream/WriteParams.java.

See also Objects.checkFromIndexSize if you wanna use that instead. Also the if len == 0 check is probably redundant, i doubt it makes any difference given the condition needs to be checked before entering the loop. Paul.
