JavaFX 12 GridView

See original GitHub issue

Hello! I have problems with the GridView on JavaFX 12 and Java 12. I just migrated from Java 8 to 12. If I am commenting out, everything is fine. I already found issues in you bitbucket, but they seemt to be closed and solved. Is there anything I could do wrong?
