RFR: JDK-8225386: test for JDK-8216261 fails in Windows

[Vicente Romero]

Please review the fix for [1] at [2]. Windows is not happy with the 
newline character introduced in a golden String in the fix for 
JDK-8216261. This fix is validating the output without using new line 
characters,

Thanks,
Vicente
