[8u] RFR(T) 8248643: Remove extra leading space in JDK-8240295 8u backport

[Zhengyu Gu]

Hi,

Please review this trivial change that removes extra leading space in 
JDK-8240295 backport.

Kevin pointed out 8u should not follow later version, where more 
information printed on the same line [1].

Bug: https://bugs.openjdk.java.net/browse/JDK-8248643

Thanks,
