Current java/math/BigInteger/LargeValueExceptions.java requests -Xmx4G. This is excessive, as test needs only ~1G on default x86_64, or even with -XX:-UseCompressedOops.

Requesting 4G makes test fail on x86_32, which is very unfortunate.

Reducing to -Xmx2g makes test pass on x86_32 without breaking x86_64:
