(In reply to Dusan Balek from comment #13)
> Do you have a reproducible test case?

Yes, I tried it again today and finally reproduced it as follow:

public enum SampleEnum {

    VALUE_1("1", VALUE_2),
    VALUE_2("2", VALUE_1);
    private final String value;
    private final SampleEnum e;

    private SampleEnum(final String value) {
        this.value = value;
        this.e = sampleEnum;
    }

    public abstract SampleEnum getSampleEnum()

    public String getValue() {
        return value;
    }

}

I hope it helps. The issue happened after I removed "final SampleEnum sampleEnum" as constructor parameter.
