Closed as program error.
Error Message: An alternate hash algorithm for java.lang.String is introduced to avoid the hash collision in put/get operations of Hash related collection maps like Hashtable, HashMap, etc . Stack Trace: N/A .
The current hashing algorithm is more predictable and can cause hash collision in put/get operations of Hash related collection maps like Hashtable, HashMap, etc. The alternate hash implementation will avoid the hash collision by introducing a random factor. Due to the introduction of random factor, the order of retrieval of elements from the collection maps can differ when the new hash algorithm is used. As documented in the API specification, there is no guarantee as to the order of the map; in particular, it does not guarantee that the order will remain constant over time. Application should make sure that they removed any such dependency before enabling the alternate hash algorithm. By default, the new hashing algorithm is disabled. It will be in affect only when the map capacity reaches the hashing threshold which can be set using Java command line argument -Djdk.map.althashing.threshold=n.
This defect will be fixed in: 5.0.0 SR14 . The JDK has been equipped with an alternate hash implementation which avoids the hash collision in put/get operations of Hash related collection maps
