Why does Cosmo fail to create the Derby database when being built on Mac OS X?
• A: Because there is a problem with Derby 10.1.1.0 on OS X 10.3 (with JDK 1.4) and OS X 10.4 (with JDK 1.5). The solution to this is documented at the Derby FAQ site. Place your derby.properties file in the top level source directory and, if you dist Cosmo and run it out of that directory, into the top level dist directory. Note that Apple has issued an update to JDK 1.5 which solves this problem. Also, in 0.2.4 we have updated to Derby 10.1.2.1 which works around the issue as well.
