>             Project: Derby
>          Issue Type: Bug
>          Components: JDBC, Network Client
>    Affects Versions: 10.2.1.6, 10.2.2.0, 10.3.1.4
>         Environment: Windows XP SP2

> Java Version:    1.6.0_02
> Java Vendor:     Sun Microsystems Inc.
> Java home:       C:\Program Files\Java\jre1.6.0_02
> Java classpath:  derbytools.jar
> OS name:         Windows XP
> OS architecture: x86
> OS version:      5.1
> Java user name:  Ma
> Java user home:  C:\Documents and Settings\ma
> Java user dir:   c:\tools\derby\lib
> java.specification.name: Java Platform API Specification
> java.specification.version: 1.6
> --------- Derby Information --------
> JRE - JDBC: Java SE 6 - JDBC 4.0
> [C:\tools\derby\lib\derbytools.jar] 10.3.1.4 - (561794)
> The following code fails:
>     // Data is a byte[] vector
>     ByteArrayInputStream is = new ByteArrayInputStream( data);    
>     String sql = "UPDATE MyTable SET FContents=? WHERE FName='" + name + "'";
>     PreparedStatement ps = conn.prepareStatement( sql);
>     ps.setBinaryStream( 1, is, data.length);
>     
>     if( ps.executeUpdate() == 0)
>     {
>         // it throws an exception here if the data array us larger then around 32750 bytes!!!
>     }
> It look's like when the size of the data[] vector is > 32750 bytes or so it throws an exception like this:
> java.sql.SQLException: A network protocol error was encountered and the connection has been terminated: A PROTOCOL Data Stream Syntax Error was detected.  Reason: 0x0. Plaintext connection attempt to an SSL enabled server?
>         at org.apache.derby.client.am.SQLExceptionFactory40.getSQLException(Unknown Source)
>         at org.apache.derby.client.am.SqlException.getSQLException(Unknown Source)
>         at org.apache.derby.client.am.PreparedStatement.executeUpdate(Unknown Source)
> The table is defined as:
>     CREATE TABLE MyTable (FName varchar(300) NOT NULL,FContents BLOB(16M) NOT NULL)
> It does loook like this only happens with the NetWork client driver, the embedded driver works fine.
