Hi,

I tried to find answers to a couple of questions I have regarding GC but found 
nothing on the Internet, I wonder if the experts here can help me out?


*         How are objects stored in the old generation when promoted from the 
young gen or survivor space? Does the JVM use something similar to the TLAB?

*         The time for a young GC pause consists stack scan, card scan and 
copying, are there command line options for me to get a time breakdown for 
those times in the GC log?

Thanks,
Jun
