Thanks, @hadim. I am happy to report that all of Fiji now melts successfully. Regarding OMEVisual I think I was wrong; the build errors I was seeing were due to missing openjfx from the compile-time environment. Anyway, now everything compiles with passing tests when unified into a consistent runtime environment with versions matching the newest pom-scijava on master. It should finally be feasible to hook up a melting pot build to the pom-scijava Travis CI, to ensure BOM consistency.
