Review request (S): 7131791 G1: Asserts in nightly testing due to 6976060

[Bengt Rutisson]

Hi all,

Can I have a couple of quick reviews for this small change:
http://cr.openjdk.java.net/~brutisso/7131791/webrev.02

This should hopefully fix the 500+ failures in the G1 nightlies. So, I 
would like to get it in before the nightlies tonight.

The issue is that we call collect() which will trigger a collection 
without protecting the memory that we just allocated for a humongous 
object. The fix (thanks Tony for helping me out!!!) is to fake an object 
and create a handle to it before we call collect.
