Michael Dick commented on OPENJPA-1957:
---------------------------------------
I'd need to see the testcase to comment. From memory, there's nothing
functionally different between the changes in 1.2.x or any other release. The
annotation parser class was refactored for new annotations in JPA 2.0 and I
just slotted this code around that.
> XML overriding column names for ArrayList attributes causes exception.

> 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.
