In some cases, there are some extraneous error messages when an opening brace is missing.   Error recovery could be improved to reduce the number of error messages for a single syntax error.

i.e. - in JDK 22, the following missing open brace on a method generates 4 error messages, one more than with JDK 21.

package tests; // TestB.java:1: error: implicitly declared class should not have package declaration
public class TestB {
    public static boolean test() // <--- missing open brace
        return true;
    }
    public static boolean test2() {
        return true;
    }
}
