RFR(S): 8013591 compiler/ciReplay/TestSA.sh fails in nightly

[Coleen Phillimore]

This looks fine.   What tests did you run to find this bug?   I think 
Jiangli ran the sajdi and probably tmtools tests and the previous 
changes looked good to me.   They passed nightly which also should have 
exercised this code.   Can we add a test somewhere since the SA insists 
on bit-rotting with everything we touch?

thanks,
Coleen
