Tiago Aurélio Rodrigues Espinha updated DERBY-3574:
---------------------------------------------------

    Attachment: derby-3574.patch

I believe this will fix the issue. The patch is just for Clob.java but the same has to be done for Blob.java, I'll do it as soon as someone with more experience than me can confirm if it's the correct way to do it.

I ran the test before and after, and it did pass with that change, but it's my first time here so any guidance is appreciated.

> Attempting to get call Blob/Clob.length() after commit or connection close does not fail if there was a previous call to length().  If no previous call was made an exception is thrown as expected.
> See attached program TestLobLength for repro with commit.  If you comment out the two lines to get the length before the commit we get the expected exception.
