If you're a beginner with OSGI I wouldn't start by mucking around with as complex an application as Eclipse. Start with a simple example instead that doesn't have any other external dependencies. The Felix examples I pointed you to accomplish that nicely.

Looks like you're using an old JRE version. Recompile the sources with the JDK/JRE with which you intend to run them.
