Whenever the code format action is triggered, the formatter adds another newline before the `//@formatter:off` comment. I'm using a slightly modified version of the "Eclipse [built-in]" code formatter settings. To reproduce the bug the following two options need to be changed:
- Line Wrapping > 'enum' declaration > Constants > Policy -> "Wrap where necessary"
- Off/On Tags -> Enabled

And here's the code in question:
---
package bugs;

public class EclipseFormatBug {
  enum MyEnum {
    // @formatter:off
    someEnumConstantWithLongName,
    anotherEnumConstantWithAnEvenLongerName,
    stillAnotherEnumConstant;
    // @formatter:on
  }
}
---

Reproducible: Always

This bug is still present in the 4.4 release.

This problem no longer occurs after the formatter redesign.
