Rick Curtis updated OPENJPA-2482:
---------------------------------
Description:
We encountered the following stacktrace[1] when processing the results of a
very complex query.
After much debugging I found that the net of the problem is that in SelectImpl
we cache column aliases(cachedColumnAlias_) keyed off a given
org.apache.openjpa.jdbc.schema.Column, but a given column might map to multiple
aliases(depending on the PathJoins @see
SelectImpl.SelectResult.containsInternal). It appears that under normal
circumstances it is okay that we continually overwrite aliases, but for this
one query we were incorrectly mapping to the wrong alias. I unsuccessfully
attempted to write a unit test for a good day and I've given up on providing a
unit tests.
