RFR(XS): 8170886 - compiler/ciReplay/TestSAServer.java intermittently throws NumberFormatException

[Dmitrij Pochepko]

Hi,

please review small fix for 8170886 - 
compiler/ciReplay/TestSAServer.java intermittently throws 
NumberFormatException

Test has thrown NFE once, because of replay file parsing logic of this 
test couldn't handle case of inlining information present.

Test expected 6th column to be last, which is true for non-inlining case 
only. This fix modifies logic to specifically get 6th column of 
compilation string instead of "last" column.

I've tested it on linux-x64.

Thanks,

Dmitrij
