----------------------------------------
Hi! I have a test (to be included) where I see the same exception which was
fixed via this JIRA:
<openjpa-1.2.3-SNAPSHOT-r422266:1176024 fatal user error>
org.apache.openjpa.persistence.ArgumentException: You have supplied columns for
"org.apache.openjpa.persistence.arrays.model.XMLOneToManyEntity.xmlManyToOneList",
but this mapping cannot have columns in this context.

.......................
I see the same exception when I run my test on trunk. The kicker is, if I back
out the changes made in this JIRA, on both 1.2.x and trunk, my test passes!!
:-( Of course, with the code changes backed out, the test Mike created for the
JIRA fails. So something is not quite right/complete about this fix.
Attached is a test, named "XMLMappingIssue-trunk.test" which you can simply
apply to any OpenJPA release. I'd assume that if we fix this issue on trunk
the same fix would apply to 1.2.x........although, the fix Mike made to 1.2.x
is for some reason a bit different than the one he made to trunk so we may want
to keep this in mind and become familiar with the differences.
Does anyone have any thoughts here?
Thanks,
Heath
