Hi John,
Just want to point out that there's a difference between Java 6
compatibility and actually using the new Java 6 features / interfaces.
Derby can be run with Java 1.4, 5.0 and 6 (and 7), but most of the
source code is written based on the 1.4 specification. This is indeed
annoying at times, when you want to use nifty new features and methods.
However, this will probably continue until the community decides to drop
support for small platforms, or the small platform Java specification
moves to the Java 5.0+ level.
When it comes to Derby and IDEs, like NetBeans, you may get better
results if you define the code to be at level 1.4 rather than 5/6. You
will still get some errors, but fewer.
Since the Derby build process is rather complex, I tell NetBeans to use
the ant targets in build.xml for building the source code.
Regards,
