StructuredCacheEntry shall pass correct expected map size and loadFactor for HashMap constructor
------------------------------------------------------------------------------------------------

                 Key: HHH-6004
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6004
             Project: Hibernate Core
          Issue Type: Improvement
          Components: caching (L2)
    Affects Versions: 3.6.0
            Reporter: Sergey Vladimirov


There is a code in StructuredCacheEntry::structure that supposed to optimize usage of HashMap and not allow resizing of HashMap. But it doesn't work. To check put a breakpoint at hashmap::resize and call for StructuredCacheEntry::structure method:

        at java.util.HashMap.resize(HashMap.java:462)
        at java.util.HashMap.addEntry(HashMap.java:755)
        at java.util.HashMap.put(HashMap.java:385)
        at org.hibernate.cache.entry.StructuredCacheEntry.structure(StructuredCacheEntry.java:67)
        at org.hibernate.engine.TwoPhaseLoad.initializeEntity(TwoPhaseLoad.java:195)
        at org.hibernate.loader.Loader.initializeEntitiesAndCollections(Loader.java:982)

I believe the line

		Map map = new HashMap(names.length+2);

shall be rewritten as

		Map map = new HashMap(names.length+3, 1.0);
