Given a program counter and a java core, output the function name corresponding to the program counter

Example:

~/jframe$ cat ../umausers.out
0xfffffd7fecb65fcb
0xfffffd7fecb1b434
0xfffffd7fed154b34
0xfffffd7fed15ff04
0xfffffd7fed761d8c
0xfffffd7fecd0e5e0
0xfffffd7fec8004e7
~/jframe$ cat ../umausers.out | ./jframe ../core.1189
