webrev: http://cr.openjdk.java.net/~jld/8050397/

Hi All,

Need a webrev for a crash fix. We were getting a NullPointerException 
anytime there was more than one event in the queue.

The event data was always being written into the beginning of the queue, 
instead of the appropriate position. As a result there was never any 
data when going to read the second event off the queue. The fix was to 
advance the buffer position bbefore writing the event data.

Thanks,
Jen
