Research direction
Run the supplied Main.java reproducer with google-java-format 1.17.0 and inspect the formatter's parsing and diagnostic path for the zero-width space after println. Done means the formatter reports an understandable error that identifies the invisible character or its location, with coverage for this reproducer.
Written by the indexing model from the issue text.
Description
The following program with a zero width space after the println is executable but cannot not be formatted
public class Main {
public static void main(String[] args) {
System.out.println("hello");
}
}
