      Description

        HumongousThreshold is not aligned to MinObjAlignment. Since HumongousThreshold drives the MaxTLABSize, issuing such max-sized TLAB would leave allocation top unaligned. This readily manifests on x86_32. x86_64 is more or less safe as default alignment matches the single HeapWord.
