operation; if the target VM is not interrupted at the time
this method is
called, it is possible that new threads will be created
between the time that threads are enumerated and all of them
have been suspended.VMCannotBeModifiedException

for each live thread
in this thread group. Only the live threads in this immediate thread group
(and not its subgroups) are returned. A thread is alive if it
has been started and has not yet been stopped.ThreadReference
