Derby 10.3 Beta Available
Derby 10.3 beta
is available for testing. If you are using Derby/Java DB, you should try your local tests with this beta and make sure everything's working for you.
This page describes what's in this release. Of note are security improvements, performance improvements, and the ability to drop or rename a column using ALTER TABLE. And, as usual, a slew of bugfixes.
One thing to be aware of is that the Network Server starts with a security manager installed by default now. This is a good thing as it provides you, by default, strong protection from potentially malicious Java code running in your server.
But what this also means is that if you have Java procedures installed in your database that do funny things like file I/O or open network sockets, you may get exceptions saying you don't have permissions to do this. You can fix this by modifying the security policy file to grant permissions, or by disabling the security manager by running the Network Server with the -noSecurityManager option.
