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.

b2bd8f2 updates the Windows implementation to return `false` instead of throwing an `IOException` in the event either file does not exist. The `Misc` test is updated accordingly, thereby eliminating two platform-specific blocks.
