Oh, I was just updating the webrev to


As we've just discussed offline, the reason the 2nd jarsigner call fails is a double weakness, not only the signer's key is 512 bit, but also signer's cert is signed by a 512 key (of CA).

Therefore I update the test to use a weak signature alg -- MD2withRSA. This time I believe the weakness of CA's cert won't infect the its signature when signing signer.
