Description

When generating Java stub for enum with an abstract method results in invalid Java source. The generated source class is defined as "abstract enum".

EnumWithAbstractMethod.groovy

enum EnumWithAbstractMethod {
    ONE {
        @Override
        int getInt() {
            return 1
        }
    },
    TWO {
        @Override
        int getInt() {
            return 2
        }
    }

    abstract int getInt()
}

Driver.groovy

class Driver {

    public static void main(String[] args) {
        def stubCompiler = new JavaStubCompilationUnit(
            new CompilerConfiguration(),
            new GroovyClassLoader(),
            new File('tmp')
        )

        stubCompiler.addSource(new File('EnumWithAbstractMethod.groovy'))

        stubCompiler.compile()
    }
}

EnumWithAbstractMethod.java

public abstract enum EnumWithAbstractMethod
  implements
    groovy.lang.GroovyObject {
