> 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
> Assignee: Kathey Marsden
> Priority: Critical
> Fix For: 10.1.3.0, 10.2.0.0, 10.1.2.4
> Attachments: IsoChange.java
>
> 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);
