Hi all,
I apologise if this is not the right ML for it but I couldn=92t find exact=
ly what I was looking for when Googling the problem. I am a bit new to the =
JDI world.
I would like to inspect the stack-frame of a specific thread, I came acros=
s the StackFrame/ThreadReference classes but I couldn=92t find a way exampl=
es where their usage is shown
without connecting to the VM somehow, like a debugger would do.
Is it possible to
inspect a thread=92s stack =93locally=94 ? In my mind I could be able to h=
ave a function such as :
static void hook(Thread thread) {
thread.wait() // stop that thread
// inspect the frames of that thread doing any needed business with them
}
I=92d need this for diagnostic purposes of my application.
Thanks,
Pietro
