RFR 8022898 java/util/Spliterator/SpliteratorCollisions.java fails in HashableIntSpliteratorWithNull data provider

[Paul Sandoz]

Hi,

This patch fixes a bug in the data provider of the SpliteratorCollisions.java 
test, which was attempting to add an element to an unmodifable map.

Interestingly although this caused the data provider to barf, and therefore 
tests using such a provider were not run, it did not result in jtreg reporting 
the test-infrastructure failure.

Paul.
