COMBINE parsing fails with updated Jena - app URI scheme not supported

      Description

      I'm trying to update taverna-language to use Jena 3.6.0 (already updated in taverna-maven-parent 3-incubating-SNAPSHOT), but then taverna-robundle fails a test:

      "Resolving against bad URI <app:://4a8a0ff8-eab0-3930-8257-017dec3a8356/manifest0.xml>"

      This seems to be because Jena's IRI support now fails for non-IANA URI schemes like "app" when parsing RDF/XML - as within the COMBINE archive's metadata.

      In RO Bundle we use UUID-based app: URL scheme as specified by W3C to represent files within a Research Object zip archive.

      That means naturally when parsing RDF files within that archive that we'll use URIs like app://4a8a0ff8-eab0-3930-8257-017dec3a8356/manifest0.xml as a base URI, so that a reference "fred.doc" becomes "app://4a8a0ff8-eab0-3930-8257-017dec3a8356/fred.xml"

      A workaround would be to replace "app" with "file", pretending the UUID is a hostname, but somehow this also fails with Jena as it mangles "file://4a8a0ff8-eab0-3930-8257-017dec3a8356/fred.xml" into file:///4a8a0ff8-eab0-3930-8257-017dec3a8356/fred.xml after parsing - so it becomes tricky tyo ask the RDF model about fred.xml afterwards.

      A workaround to the workaround would be to use host-less file:/// URIs – another to drop the UUID and pretend file:/// is the root of the local file system rather than the root of the zip archive. (This would also then correctly support relative URIs like /fred.xml although those don't occur in COMBINE archive)

      Stack trace:
