Java 14 supports Record class. However this is a preview feature. We want to turn on --enable-preview ECJ option to allow us use Record class in Act application.

Now it can use System properties to pass in ECJ compiler options. E.g. to turn on --enable-preview, use

-Dorg.eclipse.jdt.core.compiler.problem.enablePreviewFeatures=enabled

Here is the full list of ECJ compiler options:
