I’m using Clojure to do the basic tutorial on displaying a shape file on
OpenJDK 11:
(-> (doto (DefaultMapContext.)
(.setTitle "Quickstart")
(.addLayer (-> (io/resource "geotools/maps/countries.shp")
(FileDataStoreFinder/getDataStore)
(.getFeatureSource))
nil))
(JMapFrame/showMap))
However, the call to JMapFrame.showMap gives a strange error that I’m not too
sure what the cause is:
tools.map.FeatureLayer[, VISIBLE]
java.lang.NoSuchFieldError: JAVA_9

It’d be great to figure out what is wrong._______________________________________________
