Subject [jira] Created: (DERBY-1044) [xa] client XAConnection.getConnection() does have the correct default isolation level if set by an earlier connection obtained from the same XAConnection

[xa] client XAConnection.getConnection()  does have the correct  default isolation level if
set by an earlier connection obtained from the same XAConnection
------------------------------------------------------------------------------------------------------------------------------------------------------------

         Key: DERBY-1044
         URL: http://issues.apache.org/jira/browse/DERBY-1044
     Project: Derby
        Type: Bug
  Components: Network Client  
    Versions: 10.1.2.3, 10.1.3.0, 10.2.0.0, 10.1.2.2    
    Reporter: Kathey Marsden
     Fix For: 10.1.2.3, 10.1.3.0, 10.2.0.0


If the isolation level is set on a connection obtained with XAConnection.getConnection() 
and then another connection is obtained from the same XAConnection, then the isolation will
not be the default READ_COMMITTED but will be the isolation level set on the previous connection.
 

See this code in checkDataSource.java
I will add a reference to this bug

               cs1 = xac.getConnection();
		printState("new handle - local ", cs1);
		cs1.close();

		xar.start(xid, XAResource.TMJOIN);
		cs1 = xac.getConnection();
                cs1.setTransactionIsolation(Connection.TRANSACTION_REPEATABLE_READ);
		printState("pre-X1 commit - local", cs1);
		xar.start(xid, XAResource.TMJOIN);
		printState("pre-X1 commit - X1", cs1);
		xar.end(xid, XAResource.TMSUCCESS);
		printState("post-X1 end - local", cs1);
		xar.commit(xid, true);
		printState("post-X1 commit - local", cs1);
		cs1.close();

		System.out.println("Some more isolation testing using SQL and JDBC api");
                //  The  initial isolation level for this connection is REPEATABLE_READ. 
Left over from the last connection.
               // It should be READ_COMMITTED
		cs1 = xac.getConnection();
		s = cs1.createStatement();
		printState("initial local", cs1);
