    ****************************************************************
    The exception occurs because the particular JDBC driver
    checks the value of the 'length' variable passed to the
    'PreparedStatement.setBinaryStream' method:
    setBinaryStream(int parameterIndex, InputStream x, int length)
    The 'length' parameter of method 'setBinaryStream' is supposed
    to be the length of the InputStream parameter. OpenJPA code is
    passing a value of '-1' for the length as the length is not
    known. Some JDBC drivers allow this value. Technically
    speaking the javadoc for 'PreparedStatement.setBinaryStream'
    doesn't state that a negative value is not acceptable or what
    should happen when a negative length is passed to
    'setBinaryStream' (which is likely why some drivers allow a
    negative value and others do not). On the other hand, it
    doesn't make sense for a length of an InputStream to be
    negative. Given this, and the fact that OpenJPA is not aware
    of the length of the stream, this fix provides a solution
    which uses a JDBC 4.0 version of 'setBinaryStream' which
    doesn't take a length. The fix will of course require JDK 6
    and a JDBC 4.0 driver runtime. The code for this fix is also
    gated by a system property.
    

Problem conclusion

  • With this fix, code has been added to allow OpenJPA code to
    use a 'PreparedStatement.setBinaryStream' which doesn't not
    take a length as an input parameter.  The code for this fix is
    enbled by a custom property. The custom propery can be set as a
    JVM system property, or can be defined in the user's
    persistence.xml file as follows:
    
    <property name="openjpa.jdbc.DBDictionary"
    value="useJDBC4SetBinaryStream=true"/>
    
    The fix for this APAR is currently targeted for
    inclusion in Service Levels (Fix Packs) 7.0.0.25, 8.0.0.5, and
    8.5.0.1 of WebSphere Application Server versions 7.0.0,
    8.0.0, and 8.5.0. Please refer to the Recommended Updates
