Description

The current requirement for detecting a non existing file URL, to have a dot in the "filename" part regardless of extension. With modular projects such url-s would become more popular, like "javafx.base" would be a part of a non existent class directory. Detecting these non existent directories as jar files could fool the SourceForBinary Queries.

Proposed solution: Try to use the extension part of the supposed to be filename to decide if it is an archive or not.
