Description Amir Karimi

I've changed the indention for Java formatter to 2 spaces. But auto indention put 4 spaces when I hit enter after a parenthesis;

Ok(
    _ <- Caret is here
)

But I have no problem with braces;

def A = {
  _ <- Caret is here 
}

I code in Scala but the problem is produced in Java as well.

[1] System.out.println(|); Press 'Enter' at location marked with | gives:
System.out.println(
    |);
[2] new Runnable() {|}; Press 'Enter' at location marked with | gives:
new Runnable() {
  |
};
On analysis, the indentation after parenthesis is computed in JavaIndenter#createReusingIndent => fPrefs.prefIndentationSize * additional where:
fPrefs.prefIndentationSize =>  'Indentation size' from the 'Indentation' tab 
additional => 'Default indentation for wrapped lines' from the 'Line Wrapping' tab.

If 'Default indentation for wrapped lines' from the 'Line Wrapping' tab is set to '1', then case [1] behaves same as case [2].

@Markus: Is this the intended behavior?

@Manju - Thanks! Setting 'Default indentation for wrapped lines' to 1 solved the problem. It was 2 by default.

Yes.
