A better fix would be:

If runtime java.lang.Integer.IntegerCache.high < dumptime java.lang.Integer.IntegerCache.high
  -- copy the initial elements from the dumptime cache array
  -- fill the rest of the cache array

that way, we will still preserve the object identity of the Integers created during dump time.

I think we need to do the same thing for the other box cases.
