Description

There is a bug in containsKey() in the Int2IntHashMap. Use this test to check for the bug:

import java.util.HashMap;
import java.util.Map;
import org.apache.uima.internal.util.Int2IntHashMap;
import org.junit.Test;

    @Test
    public void int2intTest()
    {
        Int2IntHashMap map1 = new Int2IntHashMap();
        
        Map<Integer, Integer> map2 = new HashMap<Integer, Integer>();
        
        for (int i = 1; i < 100; i++) {
            map1.put(i, 100-1);
            map2.put(i, 100-1);
        }

        for (int i = 1; i < 100; i++) {
            assertTrue("Map does not contain key ["+i+"]", map2.containsKey(i));
        }
        
        System.out.println("Reference map implementation ok.");

        for (int i = 1; i < 100; i++) {
            assertTrue("Map does not contain key ["+i+"]", map1.containsKey(i));
        }
        
        System.out.println("UIMA map implementation ok.");
    }

Fails with:

java.lang.AssertionError: Map does not contain key [65]
