Description

Take an entity class similar to the following:

public class MyEntity implements Serializable {
protected String _id;
protected ArrayList<String> myStrings = new ArrayList<String>();
.......

and a corresponding XML mapping in orm.xml:

<entity class="somepackage.MyEntity" access="FIELD">
<table name="MY_TABLE"/>
<attributes>
<id name="_id">
<column name="MYENTITY_ID" nullable="false" />
</id>
<basic name="myStrings">
<column name="MY_STRINGS"/>
<lob/>
</basic>
</attributes>
</entity>

With this configuration, the following exception can occur:

org.apache.openjpa.persistence.ArgumentException: You have supplied columns for "somepackage.MyEntity.myStrings<element:class java.lang.String>", but this mapping cannot have columns in this context.
