Guillaume Chauvet commented on OPENJPA-2344:
--------------------------------------------
The bug is due to the order of FieldMapping values read from getFieldMappings
method.
The cause of the error is due to the fact that collection "bentities" is loaded
before field "description" therefore the connection containing the clob/blob
locator is broken.
A workaround is to rename "bentities" field in the unitary test case to
"zentities" and now the test works.

> Hi,
> We have a problem with OpenJPA (2.2.1) and Derby (10.8.2.2, in server mode).
> Some of our entities use blob fields to store binary data, and clob for long
> string values. When we start our software and executing a query on the
> database like "select e form {entity} e" we get this type of stacktrace :
> <openjpa-2.2.2-QFD-r422266:1446687M fatal general error>
> org.apache.openjpa.persistence.PersistenceException: You cannot invoke other
> java.sql.Clob/java.sql.Blob methods after calling the free() method or
> after the Blob/Clob's transaction has been committed or rolled back.

> We tried default openjpa properties configuration but nothing change. We also
> looked into OpenJPA to find calls on Blob/Clob free() method,
> unsuccessfully... Is it normal to not explicitly free blob/clob fields after
