Code generation to java gives ambiguous reference to Record #778

Description

Code-generation of a VDM-SL spec with Records to Java gives the following error:
Reference to Record is ambiguous [ERROR] both interface org.overture.codegen.runtime.Record in org.overture.codegen.runtime and class java.lang.Record in java.lang match

as of JDK 14, Record has become part of Java.Lang. This means, that it is default imported.
So import org.overture.codegen.runtime.*; indeed brings in Record, but it does not override the Java.Lang.Record. And therefore becomes ambiguous. As I understand it, importing record explicitly should solve it.
I.e. replace import org.overture.codegen.runtime.*; with import org.overture.codegen.runtime.Record
