Yes, you have discovered a bug in Jaybird that was introduced in April this
year. I am really-really surprised that it was not discovered until now.

The only solution to it is to avoid using scrollable and/or holdable result
sets. Or you can fix it by using either ResultSet.getBlob() or
ResultSet.getBinaryStream() methods.

I hope to make a bugfix release this weekend, or beginning of next week at
latest.

Thanks!
