Description:
When executing a named query against a database within an explicitly opened
transaction, after 10 successful executions the program hangs.
The problem occured when we started migrating from openJPA 2.2.0 to 2.4.3
I have tested against DB2 and Oracle databases with the same results. I suspect
the problem arises for any relational DB.
I have attached a simple maven project that will demonstrate the bug.
Under 2.2.0, the test runs fine.
When the query is changed to a native query, the test runs fine.
Debugging the openJPA code, I found suspicious code in class
org.apache.openjpa.jdbc.kernel.JDBCStoreQuery, method executeBulkOperation,
line 587:
try {
{{ if (conn.getAutoCommit())}}
conn.close();
{{ } catch (SQLException se) {}}{{}}}{{}}
The connection in case will not be returned to the pool as the conn.close() is
not executed wthin a transaction. So when committing, the ref count will not be
zero when the transaction ends and the underlying JDBC connection will not be
closed.

Description:
When executing a named query against a database within an explicitly opened
transaction, after 10 successful executions the program hangs.
The problem occured when we started migrating from openJPA 2.2.0 to 2.4.3
I have tested against DB2 and Oracle databases with the same results. I suspect
the problem arises for any relational DB.
I have attached a simple maven project that will demonstrate the bug.
Under 2.2.0, the test runs fine.
When the query is changed to a native query, the test runs fine.
Debugging the openJPA code, I found suspicious code in class

line 587:

conn.close();
{{ } catch (SQLException se) {}}

The connection in case will not be returned to the pool as the conn.close() is
not executed wthin a transaction. So when committing, the ref count will not be
zero when the transaction ends and the underlying JDBC connection will not be
closed.
