-------------------------------------------------------------------

I did not look deeper into the problem myself, yesterday I just made the 
project build in Eclipse correctly (you guys have really odd project structure, 
perhaps it's legacy, I understand). I'll investigate how we could better handle 
the binaries. To me a fix that just limits functionality is a recognition of 
insolvency, no offence.

>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 10.11.1.1
>         Environment: does not matter

> Since migrating from derby 10.7.1.1 to 10.11.1.1 really innocent code stopped 
> working: retrieving resultset column data using column names if resultset 
> contains blobs stopped working.
> I am attaching a maven project with a unit test which proves the issue. If in 
> pom.xml you change the version to 10.7.1.1 the test will pass. We are using 
> spring-jdbc' queryForMap() which traverses resultset metadata and queries 
> attributes by their column labels. Used to work before.
