In certain situations, when braces placement is configured to "New Line", NetBeans determines an incorrect indentation level. Example ("<caret>" indicates the position of the caret):

class Test
{
    protected class Inner
    {
        private final Object test = new Object()
        {
            private void test()
            {
                if ("test" != null)
                    <caret>
            }
        };
    }

    @Override
    public String toString()
    {
        return super.toString();
    }
}

Typing "{" incorrectly results in:

class Test
{
    protected class Inner
    {
        private final Object test = new Object()
        {
            private void test()
            {
                if ("test" != null)
            {<caret>
            }
        };
    }

    @Override
    public String toString()
    {
        return super.toString();
    }
}

The expected result would be:

class Test
{
    protected class Inner
    {
        private final Object test = new Object()
        {
            private void test()
            {
                if ("test" != null)
                {<caret>
            }
        };
    }

    @Override
    public String toString()
    {
        return super.toString();
    }
}

Strangely, the error occurs only when the toString() method declaration is present.
