Unnecessary line breaks and missed (maybe?) line breaks

What happened?

Hello everyone, I am using palantir 2.43.0 in a pretty large codebase through the spotless gradle plugin 6.25.0 and with gradle 8.7. Today I came around this:

private String toString(final String indent) {
    return indent
            + name
            + (parameters.isEmpty()
                    ? ""
                    : "\n" + parameters.stream().map(s -> indent + s).collect(Collectors.joining("\n")))
            + (sons.isEmpty()
                    ? ""
                    : "\n"
                            + sons.stream()
                                    .map(s -> s.toString(indent + "  "))
                                    .collect(Collectors.joining("\n")));
}

What did you want to happen?

Maybe something more like this, to avoid unnecessary line breaks.

private String toString(final String indent) {
    return indent
            + name
            + (parameters.isEmpty()
                    ? ""
                    : "\n" + parameters.stream()
                            .map(s -> indent + s)
                            .collect(Collectors.joining("\n")))
            + (sons.isEmpty()
                    ? ""
                    : "\n" + sons.stream()
                                    .map(s -> s.toString(indent + "  "))
                                    .collect(Collectors.joining("\n")));
}

I understand that it is a bit specific but I want to understand if it is an error on my side caused by ignorance and misconfiguration or if it is something that palantir can do.

Reproduce the formatting of the supplied toString method with palantir 2.43.0 through the Spotless Gradle plugin 6.25.0 on Gradle 8.7, then compare the actual output with the requested output. Trace the formatter behavior responsible for the lambda and stream line breaks; done when the behavior is explained or the output matches the example without an incorrect configuration change.
