Extract method revival
Project Lead: Benjamin Muskalla (IRC: benny`work)
Mentor: Markus Keller
This project is part of the Google Summer of Code 2009
JDT already provides several very good refactorings like Extract method. Despite the fact they are behave very good there are still some unresolved bugs and open enhancement requests. The project will take the "Extract method" refactoring to the next step by resolving all (possible) bugs and trying to enhance the current functionality. As it is one of the most used refactorings in day-to-day development it really deserves some work to get all details and edge cases fixed.

Getting the source
As all the changes made to the Extract method refactoring are done by patching the existing JDT bundles there is no seperate source repository. Either you wait that JDT includes the patches in one of the next I builds or you can checkout the JDT bundles yourself and apply the patches. All changes will be contributed trough the corresponding bugs in bugzilla (see above).

Do you have a great idea for the refactoring? Just open a new feature request.
