the class DbSlashingProtection method maySignBlock.

            LOG.warn("Signing attempted for disabled validator {}. To sign with this validator" + " you must import the validator keystore using the key manager import API", publicKey);
            return false;
        }
        final BlockValidator blockValidator = new BlockValidator(h, signingRoot, blockSlot, validatorId, signedBlocksDao, lowWatermarkDao);
