[jdt-core-dev] Newbie who wants to implement a new JDT refactoring actio

[Christophe Bismuth <christophe.bismuth@xxxxxxxxx>]

Dear Community,

I'd like to contribute to Eclipse with a new refactoring action
available in IntelliJ and called "Missorted modifiers":
"This inspection reports on declarations whose modifiers are not in
the canonical preferred order (as stated in the Java Language
Specification).
Use the checkbox below to specify that annotations should always be
sorted before keyword modifiers."

I've already had a look at these articles:
http://www.ibm.com/developerworks/opensource/library/os-ast/
http://www.eclipse.org/articles/article.php?file=Article-Unleashing-the-Power-of-Refactoring/index.html
http://www.eclipse.org/articles/Article-LTK/ltk.html

But could anyone give me a hint with a sample source code or some
files to look at in the Eclipse source repository?

Thanks,
Chris
