public class MayoRetryTest

extends junit.framework.TestCase

Regression test for the retry path in MayoSigner.generateSignature(byte[]).

The retry loop accumulates three buffers (, , ) with mulAdd-style (accumulate-into) calls. All three are allocated once before the loop, so on a retry they must be re-zeroed. The reference C implementation (MAYO-C ) declares inside the function as }, i.e. fresh per attempt, while memsets and the target on failure.

The Java port hoisted 's allocation out of the loop. Without clearing on retry, the second attempt computes (stale data carried over), corrupting the signature. The KAT vectors never trigger a retry, so this is invisible to the KAT battery.

This test forces exactly one retry by overriding to fail the first attempt, then asserts the produced signature still verifies.
