In JDK-8003887, `File.getCanonicalPath` was altered to resolve symlinks on Windows. This had unintended consequences for passing a symlink to `System.loadLibrary` on Windows. The underlying Windows `LoadLibrary` API inspects the file name passed to it and adds a `.dll` extension if the it is not already present. Thus, if `System.loadLibrary` was given a symlink to a file and that file didn't have a `.dll` extension, `LoadLibrary` try to load nonexistent file and fail.

This issue has the "oca" label so we cannot engage, sorry.
