示例1: doit

// GenCollectedHeap heap.
void VM_GenCollectFullConcurrent::doit() {
assert(Thread::current()->is_VM_thread(), "Should be VM thread");
assert(GCLockerInvokesConcurrent || ExplicitGCInvokesConcurrent, "Unexpected");

if (_gc_count_before == gch->total_collections()) {
// The "full" of do_full_collection call below "forces"
// a collection; the second arg, 0, below ensures that
// only the young gen is collected. XXX In the future,
// we'll probably need to have something in this interface
// to say do this only if we are sure we will not bail
// out to a full collection in this attempt, but that's
// for the future.
assert(SafepointSynchronize::is_at_safepoint(),
