If an entity has an attribute of type Byte array and the column name is overridden in xml the following error will occur.

<openjpa-1.0.0-SNAPSHOT-r420667:566855 fatal user error>
org.apache.openjpa.persistence.ArgumentException: You have supplied columns for
"org.apache.openjpa.persistence.xml.XmlOverrideEntity.picture<element:class java.lang.Byte>", but this mapping cannot have columns in this context.
