> Backporting JDK-8344253: Test java/util/Spliterator/SpliteratorTraversingAndSplittingTest.java failed. Fixes an intermittent failure with the `java/util/Spliterator/SpliteratorTraversingAndSplittingTest.java failed` test in situations where a decrement wouldn't complete, since unsigned shift right twice would lead to decrementing estimated size by 0. Backporting alongside the related issue: JDK-8344253: https://github.com/openjdk/jdk21u-dev/pull/1895. Ran GHA Sanity Checks, and local Tier 1 and 2. Patch is clean.

Closing due to `jdk21u-fix-no` label
