> {{URL.getPath()}} produces %20 when path contains spaces.
> I suggest to rework all the uses of {{getResource()...}} to use {{Sources.of(URL)}} so there's single -point of failure- way to convert URL to File.
> This resolves Apache CI which happens to have a space in folder name.
> For the record:
> 1) {{URL.getPath()}} produces %20, so it is added to forbidden signatures
> 2) {{Paths.get(url.toURI()).toFile()}} almost works, however it fails with URL is not hierarchical for {{new URL("file:test.java")}}
> 3) {{new File(URL.toURI()}} is worse than #2
> 4) {{URLDecoder}} must not be used to decode %20, since it will convert {{+}} to spaces as well, thus it will corrupt {{test.c++}}
> 5) It looks like {{url.toURI().getSchemeSpecificPart())}} properly handles "opaque" URIs (which are relative {{file:test.java}} kind of URLs)
