Error while building POI project

[Gauntt, David]

I am getting close to my first successful build of the POI project, and have 
run into a couple of compiler errors that seem to be blocking me.  The first of 
these is


Cannot reference a field before it is defined


This is caused 100 times in RecordTypes. java.  How is it that other people are 
getting this project to compile properly but not me?  I am building in Eclipse 
ver 2018-09 under Windows 10, using Java SE 1.8.  The project is a copy of tag 
REL_4_1_0 from the Git mirror of POI.


The following code illustrates this error.  Ironically, while the error message 
says that I am trying to reference a field, the error seems to be caused by a 
method reference (UnknownRecordPlaceholder::new).


public final class SSCCE {

    static class UnknownRecordPlaceholder {
    }

    enum RecordTypes {
// Error caused by next line
        UnknownRecordPlaceholder(UnknownRecordPlaceholder::new);

        @FunctionalInterface
        public interface RecordConstructor {
            void test();
        }

        public final RecordConstructor recordConstructor;

        RecordTypes(RecordConstructor recordConstructor) {
            this.recordConstructor = recordConstructor;
        }
    }

}
