Defect 6612732

[Tom Rodriguez]

I thought that bug was closed.  The test is actually invalid since it 
isn't using the strict modifier so extra precision in the expression is 
allowed.  See 6579973.  Anyway, I've closed that bug so don't bother 
looking at it.  I tagged a couple bugs in compiler1 as openjdk-starter 
but I don't see very many in compiler2 that would be easy to pickup and 
fix quickly.
