A DESCRIPTION OF THE PROBLEM :
I have a record "RecA" and use this tool (https://github.com/Randgalt/record-builder) to create a builder "RecABuilder" for the record, which works fine.
I wanted to include the generated Builder as a generic type of another records ("RecB") parameter, like "record RecB(List<RecABuilder>){}", but this fails

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile the given class

ACTUAL -
An exception has occurred in the compiler (17.0.3). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.
