Hello, I have been using Apache Derby 10.2.2.0 for a few months, and it
has been working quite well for me.
I upgrade to 10.3.1.4 just after the release came out, and I have been
testing it out with my application.
It seems to work fine, except when I read some BLOB fields from the
database, this Exception is thrown:
java.sql.SQLTransientConnectionException: No current connection.

Are you accessing the Blob after the Connection from which is was
obtained has been closed? As described in the release notes for 10.3,
it now required that the Connection is still open in order to access the
Blob. In 10.2, small Blobs may be accessed after the connection is
closed, but not larger Blobs.
Please, check whether the Connection should still be open when the
failure occurs. If not, is it possible for you to change your
application to keep the connection open as long as needed?
