Steps To Reproduce:

public class MyTest {

    @Test
    public void testname() throws Exception {
        int i = 5, j = 6, k = 7;
        if (new String().length() != 0 &&
                (i < j && j < k)) {

        }
    }
}

Auto-format with all Java code style formatter line wrapping options set to "do not wrap" (maximum line width is for this example set to 50) leads to:

public class MyTest {

    @Test
    public void testname() throws Exception {
        int i = 5, j = 6, k = 7;
        if (new String().length() != 0 && (i < j && j < k)) {

        }
    }
}


More information:
Setting all Java code style formatter line wrapping options to "do not wrap" unwraps lines. This is especially annoying in cases where e.g. (a) a slightly more complex if condition is made up of several expressions and the developer has added explicit hard line breaks on purpose to increase readability; or (b) longer strings (e.g. for logging) are assembled  from static strings and variables and again the initial developer's choice has hard line breaks on purpose in order to be more readable. As a result the Java source code auto format cannot be applied, solely due to this single issue leading to less readability in certain cases.

Changing/fixing the "do not wrap" option to really keep the original wrapping would allow applying auto formatting at long last, while not endangering any third-party auto-formating tools vendor, because the typically hopefully offer additional advanced features anyhow ;-)
