instruction reordering did not occur , and why ?
------ Solution ---------------------------------------- ----
how do you verify ? You see bytecode ?
------ Solution ---------------------------------------- ----
studied . .
------ For reference only ---------------------------------------
should be optimized during operation due to , if instruction reordering , then the output of another thread is the null value
