jstack

void jstack(int nframes, int strsize)
void jstack(int nframes)
void jstack(void)

jstack is an alias for ustack that uses the value of the jstackframes option for the number of stack frames and the value of the jstackstrsize option for the string space size. By default, jstacksize defaults to a non-zero value. As a result, use of jstack will result in a stack with in situ Java frame translation.
