When batchLimit=-1 or >1 and an exception is caused, the params and failedObject are missing
from the resultant exception.

                 Key: OPENJPA-1550
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1550
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 1.2.2
            Reporter: Heath Thomann
            Assignee: Heath Thomann
            Priority: Minor


Exception reporting is different depending on the value of batchLimit.  To describe and demonstration
this problem, lets take the following Entitiy:

@Entity
public class Ent1 {
    @Id
    private int pk;    
    private String name;
.....
}

As a test, lets assume that we have an Ent1 with pk=200 already defined in the DB and our
test will attempt to create and persist another Ent1 with pk=200 (i.e. a duplicate key). 
In so doing we get the following exception as indicated by the batchLimit settings:

batchLimit=0 or batchLimit=1
Caused by: <openjpa-1.2.2-SNAPSHOT-r422266:889769M nonfatal store error> org.apache.openjpa.persistence.EntityExistsException:
The statement was aborted because it would have caused a duplicate key value in a unique or
primary key constraint or unique index identified by 'SQL100301111328870' defined on 'ENT1'.
{prepstmnt 33038075 INSERT INTO Ent1 (pk, name) VALUES (?, ?) [params=(int) 200, (String)
twohundred]} [code=20000, state=23505]
FailedObject: siemens75007.Ent1@19d0e0b


when batchLimit=-1 or >1
Caused by: <openjpa-1.2.2-SNAPSHOT-r422266:889769M nonfatal store error> org.apache.openjpa.persistence.EntityExistsException:
The statement was aborted because it would have caused a duplicate key value in a unique or
primary key constraint or unique index identified by 'SQL100301111328870' defined on 'ENT1'.
FailedObject: prepstmnt 33038075 INSERT INTO Ent1 (pk, name) VALUES (?, ?) [org.apache.openjpa.jdbc.kernel.JDBCStoreManager$CancelPreparedStatement]


Notice that when batchLimit=[0,1], the exception lists the prepared statement used along with
the params which caused the failure, as well as the 'FailedObject'.  Furthermore, calling
'getFailedObject' on the resultant exception will give the caller the entity which caused
the failure.  In contrast, when batchLimit=-1 or a value greater than 1, we can see that the
exception message is missing the prepared statement info, however, it is presented in the
'FailedObject'.  The params are also missing from the prepared statement.  A call to 'getFailedObject'
on the resultant exception will NOT give the caller the entity which caused the exception.
