The file has a URL but it leads to a non-existing server. The file importer will try to load metadata by calling File.updateURLMetadata(). This call is inside a try/catch block that is intended to ignore all exceptions.

Adding a debug stack trace to this method reveals:

The SocketTimeoutException is actually a subclass of InterruptedIOException and there is a special case for this that is intended to handle the "Abort" functionality by setting the Thread.interrupt() flag. This was implemented in #2226.
