Hi and thanks for your report.

Unfortunately, it does not give me anything to work on, no test case, no server/environment details and as such constitutes a free support request. If you wish we solve such problems for you on the basis of report like this, you should purchase a support contract.
On the other hand, if you want us to deal with problem here, you need to write much better problem report and attach small but complete test case.

So, what will it be?

PS: There is a regression test for just this in c/J sources under /src/testsuite.regression/BlobRegressionTest.java, you might find your answers there.

No feedback was provided for this bug for over a month, so it is

information that was originally requested, please do so and change

The reported behaviour isn't reproducible with current c/J code, connector saves and retrieves a correct number of bytes.
