Problem Querying Entity With Field Declared as an Enum Array

[JimOR]

I have an Entity class that contains a persisted field which is an array of
enum.  Whenever I attempt to query this entity, I receive an
org.apache.openjpa.persistence.ArgumentException, which seems to indicate
that we're trying to find a values() method on the array type.  Tests with
the field configured as a singleton work beautifully.

My use case is to provide persistence of ad-hoc report formats containing
columns selected from a fixed list, and I'd prefer to have a single table
row for each saved report in the db.

I'm wondering if I'm treading in unsupported ground, or am I missing
something in my enum/entity declaration.

I'm using OpenJPA 1.01 (embedded from OpenEJB 3.0) on WinXP/Java 1.5.0_14
with PostgreSQL 8.3.1

The entire stack trace is  http://www.nabble.com/file/p17656042/stacktrace
here , but the following lines look like the culprit:
Caused by: <openjpa-1.0.1-r420667:592145 fatal user error>
org.apache.openjpa.persistence.ArgumentException: null
at
org.apache.openjpa.jdbc.meta.strats.EnumValueHandler.map(EnumValueHandler.java:63)

and:
Caused by: java.lang.NoSuchMethodException:
[Lportfolio.data.entities.enums.Measure;.values()
        at java.lang.Class.getMethod(Class.java:1581)
        at
org.apache.openjpa.jdbc.meta.strats.EnumValueHandler.map(EnumValueHandler.java:60)

My entity defines the field as:
        @Column(nullable=false)
        @Basic( fetch = FetchType.EAGER ) 
        @Enumerated( EnumType.STRING ) 
        private Measure[] measures; 
        public Measure[] getMeasures() {
                return measures;
        }
        public void setMeasures(Measure[] measures) {
                this.measures = measures;
        }
and my enum declaration in part contains:
public enum Measure {
        ReInv ("Re-Invested", false),
        Invest ("Invested", false),
        Cost ("Cost", false),
        Value ("Value", false),
        AvgCost ("Avg Cost", true),
        
        private String description;
        private boolean perShare;
        private Measure(String desc, boolean per){
                this.description=desc;
                this.perShare=per;
        }
        public String desc(){return this.description;}
        public boolean pershare(){return this.perShare;}
}
