Current definition of ShenandoahThreadLocalData is odd:
static void initialize_gclab(Thread* thread) {
assert (thread->is_Java_thread() || thread->is_Worker_thread(), "Only Java and GC worker threads are allowed to get GCLABs");
assert(data(thread)->_gclab == NULL, "Only initialize once");
data(thread)->_gclab = new PLAB(PLAB::min_size());
data(thread)->_gclab_size = 0;
data(thread)->_disarmed_value = ShenandoahCodeRoots::disarmed_value();
}
Why does initialize_gclab initializes _disarmed_value? It should get its own setter.
static void initialize_gclab(Thread* thread) {
assert (thread->is_Java_thread() || thread->is_Worker_thread(), "Only Java and GC worker threads are allowed to get GCLABs");
assert(data(thread)->_gclab == NULL, "Only initialize once");
data(thread)->_gclab = new PLAB(PLAB::min_size());
data(thread)->_gclab_size = 0;
data(thread)->_disarmed_value = ShenandoahCodeRoots::disarmed_value();
}
