Harmony, Guice, and OSGi

I've recently been tinkering with Google's dependency injection framework, Guice, and getting a simple example to run under the Equinox OSGi framework. It was straightforward except that there are a couple of extra dependencies (i.e. that you couldn't infer from the source code of the example) that need to be expressed as imported/exported packages because of a code generation library, cglib, that Guice uses.

This morning, I thought I'd try running the example using the Apache Harmony JDK 5.0M1 and it ran cleanly first time. I'm very impressed since Guice makes extensive use of generics and annotations and cglib is hardly typical application code.
