      Description

        The stubs for aescrypt_encryptBlock / aescrypt_decryptBlock use a read-modify-write implementation to store the 16 Byte result to an unaligned address. Depending on alignment, we may read and write Bytes beyond the array. This is not safe because these Bytes can belong to another object in the Java heap which can get modified concurrently.
