Siegfried did a great job describing how to get involved. One thing that he mentioned that worked for me when I first started is working on unit tests and documentation. The great thing about OSS is that most projects have a lot of unit tests and you can use them to understand how the code works and how small changes affect it.=20 For Commons components, sometimes our javadoc is not as clear as it could be. Unit tests can confirm exact behavior and javadoc can be improved. I remember when I first started working on [lang], that's how I started - asking on the mailing list what exactly was meant by some vague javadoc, then confirming with unit tests and also improving the javadoc. I got to learn and the tests and javadoc were improved. Adding unit tests to open bug reports is also a great service and a good way to get into the code. Don't be bashful to ask questions about how the code works or how to get set up. Sometimes it may take a while to get a response because we have a lot of components and some don't have many active contributors; but we welcome questions about the code and documentation.
