JDK 9 RFR of JDK-8146668: Replace custom check/range functionality with check index/range methods in java.util.Objects

[Amy Lu]

8135248 and 8155794 introduced utility methods for checking indexes and 
ranges. Existing code with custom checkIndex/checkRange can be updated 
to use these methods. Please review the patch for this purpose:

bug: https://bugs.openjdk.java.net/browse/JDK-8146668
webrev: http://cr.openjdk.java.net/~amlu/8146668/webrev.01

The type of exception thrown are preserved. Custom checkIndex/checkRange 
functions that throw IOOBE are now using ‘check’ utility methods 
provided by java.lang.Objects (which also throws IOOBE), functions that 
throw other exceptions use jdk.internal.util.Preconditions to preserve 
exception types, with the help of new BiFunction vars.

I'd like to get this in JDK 9 if it's not too late, otherwise, JDK 10.

Thanks,
Amy
