Can I use Camel on Java 1.4
Apache Camel was developed to run on Java 1.5 or later to take advantage of the new language features like generics and annotations together with using the Java 5 concurrency code. Starting with version 2.7.0, only Java 1.6 is supported.
Starting with version 2.10.0, Java 1.7 is supported, but not required.
