title: Java G1 garbage collection in production
body: <p>Since Java 7 is going to use the new G1 garbage collection by default is Java going to be able to handle an order of magnitude larger heap without supposed "devastating" GC pause times?  Has anybody actually implemented G1 in production, what were your experiences?</p>
  
  <p>To be fair the only time I have seen really long GC pauses is on very large heaps, much more than a workstation would have.  To clarify my question; will G1 open the gateway to heaps in the hundreds of GB? TB?</p>
