I'm confusing on How to relate the nid in Java thread dump with pstack putput.
I need to find which Thread consuming CPU got information by executing command:prstat -L
but when i look at thread dump , each thread  has nid value. but output of prstat -L has lwp id(which is in decimal)
I heard we can get the nid information pstack. but i could not able to find out from pstack.

Please let if anybody have on this or any other alternative ways..

basically I need to figaure out what thread is doing..(which is consuming high COU usage)

"Thread-598" daemon prio=10 tid=0x01b48410 nid=0x3f2 runnable [0x7a581000..0x7a581988]

don't think you can, that nid is just an address, not the actual id.
