> Key: DERBY-3085
> URL: https://issues.apache.org/jira/browse/DERBY-3085
> 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
> Reporter: Mikael Aronsson
>
> 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.
