RFR 8025535: Unsafe typecast in java.util.stream.SortedOps

[Paul Sandoz]

Hi,

Please review the following patch that checks size limits for the sorted operation and fails quickly rather than failing with an obscure ISE or an OOME later on:

  http://cr.openjdk.java.net/~psandoz/tl/JDK-8025535-sorted-unsafe-type-cast/webrev/

Tests have been added that assert for both SIZED and non-SIZED (at pipeline construction) inputs to sorted().

Paul.
