4.x: Cleanup + lambda instead of inner class check

[akarnokd]

Runs the following regex against all java files to detect anonymous inner class creation:

new\s+\w+(?:\s*<(?:[\s\w<>(\[\])?,.?]|\s*<[\s\w<>(\[\])?,.?]*>)*>)?\s*\([^)]*\)\s*\{

It will have all the file and line numbers in the crash exception.

If an anonymous inner class has state, use the /* NFI */ comment between the ) and {:

- new SomeClass() {
+ new SomeClass() /* NFI */ {
