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
