Question

I use JAXB 2 to parse an XML file against an XSD schema and the XML tags are automatically unmarshalled during ant build to Java classes. Some enums are created. The code is:

@XmlType(name = "binQuality")
@XmlEnum
public enum BinQuality {

    GOOD,
    BAD,
    UGLY,
    NULL;

    public String value() {
        return name();
    }

    public static BinQuality fromValue(String v) {
        return valueOf(v);
    }
}

In my code I call:

BinQuality bq = BinQuality.valueOf(him.getToBinQuality());

in a loop and I get the exception only in the 91st iteration.

******* UPDATED *******

him.getToBinQuality() does return a valid enum (GOOD/BAD/UGLY/NULL). Below is an excerpt of logs.

This seems really mysterious.

Java version used is 1.5.

Appreciate it.

Answer 1

This is because no enum value could be found for your 91th entry. What is the value of the failed String?
