Support java 17

[egorklimov]

Hello!

I tried to run evosuite with Java 17. But it failed due to java modules error: module java.base does not "opens java.util" to unnamed module.

I added a library that supports opening models in runtime and updated xstream and asm versions. I also tried to add add-opens to jar manifest, but that didn't help. This solution is maybe not so good because it opens all modules, maybe we should choose a set of modules and only open them.

It now at least works on java 17, but maybe we need to update the instrumentation too. I'm not familiar with the evosuite instrumentation, but if I can help support java 17 please let me know what I should do ;)

I also tried this solution with java19 and it hangs without any log. I'll try to debug it

I tried it on this simple app:

package org.example;

public class Main {

    public boolean is2(int target) {
        return target == 2;
    }

    public static void main(String[] args) {
        System.out.println(new Main().is2(2));
        System.out.println(new Main().checkObject(new Circle(1)));
    }

    record Human(String name, int age, String profession) {}
    record Circle(int radius) {}

    public String checkObject(Object obj) {
        if (obj instanceof Human h) {
            return "Name: %s, age: %s and profession: %s".formatted(h.name(), h.age(), h.profession());
        } else if (obj instanceof Circle c) {
            return "This is a circle %d".formatted(c.radius);
        }
        return "It is an object";
    }
}

And got the following tests:

      String string0 = main0.checkObject(object0);
      assertEquals("It is an object", string0);
  }

  public void test1()  throws Throwable  {
      Main main0 = new Main();
      boolean boolean0 = main0.is2(3);
      assertFalse(boolean0);
  }

  }
}

Could you restart tests? I tried them locally and it is green, maybe it is a flaky test
