JENA-1784 CacheSimple doesn't check keys for equality
> 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
> Assignee: Andy Seaborne
> Priority: Major
> Time Spent: 1h 10m
> Remaining Estimate: 0h

> 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}
