That is fair. Do you know how one could create a reliable test for performance that would fail without the fix and succeed with the fix?

I think the allocation is a reasonable proxy for the duration in this case, and the allocation is more-or-less easy to measure and test if the JVM supports `getCurrentThreadAllocatedBytes`.
