XA end() fails with Connection is closed error

I am testing ClientXADataSource.
It fails when end() is called - here is the output fromn my test program.

Running test org.simplejta.xatests.common.Test1
autocommit = false
No of rows Affected 1
autocommit = true
No of rows Affected 1

The test program is:

/*

• Test case for multiple logical connections between start() and end().
  */
  package org.simplejta.xatests.common;

import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;

import javax.sql.XAConnection;
import javax.sql.XADataSource;
import javax.transaction.xa.XAResource;
import javax.transaction.xa.Xid;

public class Test1 extends TestCase {

public void doTest(XADataSource ds) throws Exception

{ // Get a XA connection to the underlying data source XAConnection pc1 = ds.getXAConnection(); // Get the XA Resource XAResource xar1 = pc1.getXAResource(); // Create an Xid Xid xid1 = Utils.createXid(1); // Start the XA transaction xar1.start(xid1, XAResource.TMNOFLAGS); // Get a Logical Connection Connection conn1 = pc1.getConnection(); System.out.println("autocommit = " + conn1.getAutoCommit()); // Do something with conn1 doSomeWork1(conn1, 50); // Close the logical connection conn1.close(); // Get another logical connection conn1 = pc1.getConnection(); System.out.println("autocommit = " + conn1.getAutoCommit()); // Do something with conn1 doSomeWork1(conn1, 51); // Close the logical connection conn1.close(); // END the branche xar1.end(xid1, XAResource.TMSUCCESS); // Prepare the RMs int prp1 = xar1.prepare(xid1); // Commit transaction xar1.commit(xid1, false); // Close physical connection pc1.close(); }

private void doSomeWork1(Connection conn, int deptno) throws SQLException

{ Statement stmt = conn.createStatement(); int cnt = stmt .executeUpdate("INSERT INTO dept VALUES (" + deptno + ", 'BSD', 'LONDON')"); System.out.println("No of rows Affected " + cnt); stmt.close(); stmt = null; }

}

This test works fine with EmbeddedXADataSource. It also works fine with Oracle.

Also, note that this error seems similar to the error I am getting with DB2 using the DB2 type 4 driver.

Curiously, the error appears to corrupt the database. Subsequent attempts to start the database gives an error.
