Description:
Reporting for Mamta Satoor, filed on Derby-dev list.

I think there is a bug in Derby when the user code tries to get the
Connection object from XAConnection "inside" the global transaction.
In this case, the Connection object gets created with un-supported
holdability. Look at the following piece of code and it's output to
see what exactly happens
    EmbeddedXADataSource dscsx = new EmbeddedXADataSource();
    dscsx.setDatabaseName("wombat");
    XAConnection xac = dscsx.getXAConnection("fred", "wilma");
    XAResource xr = xac.getXAResource();
    xid = getXid(27, (byte) 21, (byte) 01);
    xr.start(xid, XAResource.TMNOFLAGS);
    conn1 = xac.getConnection();
    System.out.println("This is a bug. Connection's holdability should
have been CLOSE_CURSORS_AT_COMMIT since it is in the global
transaction");
    System.out.println("CONNECTION(in xa transaction) HOLDABILITY " +
(conn1.getHoldability() == ResultSet.HOLD_CURSORS_OVER_COMMIT));
    System.out.println("Autocommit on Connection inside global
transaction has been set correctly to " + conn1.getAutoCommit());
    xr.end(xid, XAResource.TMSUCCESS);
The output for the above piece of code is
    This is a bug. Connection's holdability should have been
CLOSE_CURSORS_AT_COMMIT since it is in the global transaction
    CONNECTION(in xa transaction) HOLDABILITY true
    Autocommit on Connection inside global transaction has been set
correctly to false
