I'm not sure I get as to why the test fails on 32 bits - in the sense that it does not seem to rely on platform specific assumptions (at least on a quick look). On top of my head I'm not aware of what might have caused this to start working again in JDK-8254162, so maybe some more investigation is required?

At the very least we should only disable the problematic spliterator test, which is, I believe "testSegmentSpliterator" - and leave the other running, which is useful, as this is an important stress test for spliterators.
