Sets the amount of time (in milliseconds) a softly reachable object is held Lively around the heap following the previous time it absolutely was referenced. The default price is a person next of life time for every absolutely free megabyte during the heap.

Applies multiple arguments while in the buy that they appear about the official statement command line. A number of -Xlog arguments for a similar output override one another of their offered get.
