Since Netbeans 7.0 beta, following regression in autoformatter occurs:

After each autoformatting, one more white space is inserted before the open curled brace ("{").

7.0 RC2 didn't have this bug.

NOTE: I observed this behavior already in some older betas of 6.9, but this was fixed afterwards. I don't know the bug ID.

public class _NBFormattingRegression {

	// first "autoformat"
	private final Runnable r1 = new Runnable() { // <-- !!!

		@Override
		public void run() {

	// second "autoformat"
	private final Runnable r2 = new Runnable()  { // <-- !!!

		@Override
		public void run() {
		}

	};

	// third "autoformat"
	private final Runnable r3 = new Runnable()   { // <-- !!!

		@Override
		public void run() {
		}

	};

	// and to infinity and beyond! ;)
