Removing unchecked exception in Java without supressing the warning

Question

I have a method that does comparison of two jsons.

import org.json.JSONException;
import org.junit.Test;
import org.skyscreamer.jsonassert.*;
import org.skyscreamer.jsonassert.comparator.CustomComparator;

public class TestClass {

    @Test
    public void jsonCompareTest() throws JSONException {
        JSONAssert.assertEquals("{x: 1, time:123}", "{x: 1, time:234}",
                                new CustomComparator(
                                JSONCompareMode.LENIENT,
                                Customization.customization("time",
                                                            (ValueMatcher)(o1, o2) -> true)));
    }

}

So it works as expected, no issues. However, the following section is highlighted in yellow!

(ValueMatcher)(o1, o2) -> true

It gives following warning:

Unchecked assignment: 'org.skyscreamer.jsonassert.ValueMatcher' to 'org.skyscreamer.jsonassert.ValueMatcher<java.lang.Object>'
Signals places where an unchecked warning is issued by the compiler, for example:
    void f(HashMap map) {
        map.put("key", "value");
    }

If I put the following above the class, it disappears:

@SuppressWarnings("unchecked")

But is there any other way to properly fix it rather than suppress the warning?!

Please give example in the current context
