Mamta A. Satoor commented on DERBY-6214:
----------------------------------------
Little more info on the exception raised by client server test cases. The
exception is thrown by the server side code in
org.apache.derby.iapi.types.ReaderToUTF8Stream:read(byte b[], int off, int
len). The exception thrown is ('Stream has already been read and end-of-file
reached and cannot be re-used.: java.io.EOFException'.)
Part of org.apache.derby.iapi.types.ReaderToUTF8Stream:read is copied below for
reference
public int read(byte b[], int off, int len) throws IOException {
// when stream has been read and eof reached, stream is closed
// and buffer is set to null ( see close() method)
// since stream cannot be re-used, check if stream is closed and
// if so throw an EOFException
if ( buffer == null )
throw new EOFException(MessageService.getTextMessage
(SQLState.STREAM_EOF));

> URL: https://issues.apache.org/jira/browse/DERBY-6214
> Project: Derby
> Issue Type: Bug
> Affects Versions: 10.8.3.0, 10.9.1.0
> Reporter: Rong Qu
> Assignee: Mamta A. Satoor
> Attachments: Derby6214.java, Derby6214_setup.sql,

>
> The issue is specific to the DerbyNet client driver, and doesn't seem to
> occur using embedded Derby.
> "PreparedStatement.setObject(int, Object, Types.CLOB)". It seems to be a
> problem updating a CLOB column with a parameterized value using the DerbyNet
> client driver, and if the update SQL ends up updating more than one row. I
> attached a simple test case that just uses JDBC to reproduce the error. The
> exception looks like this:
> org.apache.derby.client.am.BatchUpdateException: Non-atomic batch failure.
> The batch was submitted, but at least one exception occurred on an individual
> member of the batch. Use getNextException() to retrieve the exceptions for
> specific batched elements.
