I am trying to use an example https://vadimtropashko.wordpress.com/2019/08/01/arbori-semantic-actions/, but it is not working.
I added a rule WrongToDateNumOfArgs:
After restarting IDE Custom Syntax Rules pane show error PlainLanguageSupport cannot be cast to ArboriLanguageSupport:
java.lang.ClassCastException: oracle.javatools.editor.language.plain.PlainLanguageSupport cannot be cast to oracle.dbtools.raptor.plsql.structure.arbori.ArboriLanguageSupport

When i removed the {java script} after -> at end of rule (custom_syntax.arbori file at home dir) and restarted the IDE, i see the new rule WrongToDateNumOfArgs in Syntax Colors/Available Styles, but changing the color settings does not affect the code highlighting of to_date( defg ) as in example.
