We noticed that the following in build.properties are wrong in the jfx11u repo:

jfx.build.jdk.version=11
jfx.build.jdk.buildnum=9
jfx.build.jdk.version.min=10
jfx.build.jdk.buildnum.min=46

The minimum should be set to JDK 11+28. The version should be set to whatever Gluon is using to do their builds (either 11+28 or 11.0.X+NN).

I note that these properties are not actually being read for the JavaFX 11.0.X builds, else they would fail (which is why this is only a P4 bug). We should consider fixing this to avoid confusion.
