6e6035505c zero heap space ahead of time when allocating raw storage and garbage collecting, not when allocating individual objects 
This helps us support the Java Memory Model without adding a memory
barrier to every object allocation.  It's also potentially more
efficient, since we zero out each heap segment all at once instead of
bit-by-bit with each object allocation.

13a535d1c6 Added a getContentLength() method to URLConnection 
This is particularly important if you want to get the number of bytes of a
resource loaded by the class loader:
  getClass().getResource("myFile").openConnection().getContentLength()

8e5ce11047 refactor memory management code 
We now support immortal objects, which the GC will scan for references
but not consider for collection.  On x86_64, we allocate JIT code memory
via mmap, which lets us map memory into the bottom 2GB of the address
space, ensuring that 32-bit relative jumps and calls work.
