On second thought, I don't think the sections beginning here, at line 118, and below, at line 139, should differ between Unix and Windows. I think it would be better to change the Windows implementation in the context of this request to return false instead of throwing `IOException`, and investigate any more complicated link checking when addressing https://bugs.openjdk.org/browse/JDK-8365626.
