When testing the Go Plugin, which is a ToolInstaller and so makes use of this FilePath API, I've seen that it consistently fails to download certain files — regardless of which OS Jenkins is running on, and from which web server the files are being downloaded from (and whether HTTP or HTTPS).
An typical stacktrace:
java.io.IOException: Failed to install https://storage.googleapis.com/golang/go1.6.2.darwin-amd64.tar.gz to /tmp/jenkins/tools/Go_1.6.2

The issue can be reproduced like this:
FilePath filePath = new FilePath(new File("..."));
filePath.installIfNecessaryFrom(new URL(url), null, null);
