-----------------------------------------

             Summary: CacheSimple doesn't check keys for equality 
                 Key: JENA-1784
                 URL: https://issues.apache.org/jira/browse/JENA-1784
             Project: Apache Jena
          Issue Type: Bug
            Reporter: Pavel Mikhailovskii


CacheSimple identifies keys solely by their hash codes, so that two keys with same hash code are treated as equal, and values stored with one key can be retrieved with another.

A test that currently fails:
{code:java}
@Test
public void testSameHash() {
  Cache<String, Integer> cache = new CacheSimple<>(10);
  assertEquals("Aa".hashCode(), "BB".hashCode());
  cache.put("Aa", 1);
  assertFalse("Keys with same hash code should not be considered equal", cache.containsKey("BB"));
}
{code}
