| Hi,
| 
| Please review this simple code cleanup:
| 
|    http://cr.openjdk.java.net/~xuelei/8159009/webrev.00/
| 
| The javax.crypto.ExemptionMechanism.finalize() is implemented as:
| 
|     /**
|      * Ensures that the key stored away by this ExemptionMechanism
|      * object will be wiped out when there are no more references to it.
|      */
|      protected void finalize() {
|         keyStored = null;
|         // Are there anything else we could do?
|     }
| 
| Plan to remove this finalize() method as it really does nothing more
| than the default finalizer but hurt the performance.

Ok fine, but can't we do better than saying "hurt the performance", by
actually providing how we measured this and what is it actually saving?
This does not look like a hot code path to me...
