Is there any x86bg equivalent for jave debug ?

[sendersu]

what is the meaning of static debugging?
deubgging by its nature is always dynamic
you debug - you do step into, step over, tracing etc
CPU registers are changing each and every time...so not clear

regards java debugger- I've tried in the past some tool named snoop dbg (if I recall it right)
but I never had any success.
so for me its terra incognita
maybe due to java is dieying (is it?) or it is very limited in use nowadays...

I"ve also heard some masters could use NB to debug java (wihtout sources) but I can't say for sure.
