It is not clear to me why we do, so I was going to follow up with an RFE
to investigate & suggest the removal of -base if unnecessary.

>> Please review this fix to ignore linker warning (LNK4281). This is a new linker warning generated by VS2017 v15.5 to "to point out any 64-bit image specified to link with a lower than 4GB base address doesn't get best ASLR optimization". The Hotspot jvm.dll is specifically linked with -base:0x8000000. As recommended by https://developercommunity.visualstudio.com/content/problem/160970/upgrading-from-154-to-155-throw-lnk4281-warning.html, this linker warning can be suppressed with -ignore.
