While compiling:

public class X {
    public static void main(String [] args) {
        Object o = args;
        if (o __matches int s) {
            System.out.println("Broken");
        } else {
            System.out.println("!Broken");
        }
    }
}


I get:

/home/srikanth/tmp/X.java:4: error: bad operand types for binary operator '=='
        if (o __matches int s) {
              ^
  first type: int
  second type: Object
1 error

This is surprising.
