[13] RFR 8228341: SignTwice.java fails intermittently on Windows

[Weijun Wang]

Please review the patch below. This test signs the same jar multiple times. 
It's mainly about making sure the manifest and signature file can be updated 
correctly. There is no need to try different key algorithms. We can also use a 
faster digest algorithm.

Thanks,
Max
