Example 1 with ReferenceMap

use of org.apache.commons.collections4.map.ReferenceMap in project commons-collections by apache.

the class ReferenceMapTest method testDataSizeAfterSerialization.

 * Test whether after serialization the "data" HashEntry array is the same size as the original.<p>

 * See <a href="https://issues.apache.org/jira/browse/COLLECTIONS-599">COLLECTIONS-599: HashEntry array object naming data initialized with double the size during deserialization</a>
