----------------------------------------
I'm seeing an intermittent failure when running with the patch. The failure
happens in jdbcapi.LobStreamsTest.
I have seen the following two stack traces:
1)
testBlobWrite3Param(org.apache.derbyTesting.functionTests.tests.jdbcapi.LobStreamsTest)java.io.IOException:

On my system the problem is seen in maybe one out of ten or fifteen runs. I
can't see the new code being run as part of the test, so I'm not sure what's
going on here.

> PreparedStatement ps = c.prepareStatement("values cast(? as blob)");
> int len = 32 * 1024;
> ps.setBinaryStream(1, new ByteArrayInputStream(new byte[len]), len);
> ResultSet rs = ps.executeQuery();
> while (rs.next()) {

> If len < 32K there is no error.
