Rather than a feature, it's Derby's support for that environment.

Today Derby supports from a single jar

J2SE 1.3 - requires JDK 1.3 to build
J2SE 1.4 - requires JDK 1.4 to build
J2SE 5.0 - runs in, doesn't yet take advantage of any J2SE 5.0 feature
           (except through reflection for BigDecimal.toPlainString)


Continuing that forward, I imagine in the future Derby will support from
a single jar

J2ME/CDC/Foundation/JSR169 - requires foundation and JSR169 jars to build
J2SE 1.3 - requires JDK 1.3 to build
J2SE 1.4 - requires JDK 1.4 to build
J2SE 5.0 - requires JDK 1.5 to build
           (takes advantage of J2SE 5.0 features)
