Interesting use of -XX:+DisableExplicitGC. Does this recent SPEC benchmark do explicit GC calls? Not a best development practice…
The flag is used to disable RMI induced GCs, which happen at certain point of the lifecyle. Calling System.gc() is a \*bad\* thing in general, don’t do it unless you know you need to GC.
Thanks for the clarification!
