Description
For the suppressed exception feature added as part of the ARM proposal submitted to Project Coin (6911258), some refinements would be helpful:

* Add a check for trying to suppress yourself
* Change the serial form of suppressed exceptions to use arrays rather than a java.util.List
Since Throwable already has references to java.util now, removing such references from the serial form alone is not judged to be worthwhile.
