You can use valgrind. It records data in a file which you can analyse later using a proper gui like KCacheGrind

A usage example would be :

valgrind --tool=callgrind --dump-instr=yes --simulate-cache=yes your_program

It'll generate a file called callgrind.out.xxx where xxx is the pid of the program

edit: unlike gprof valgrind works with many different languages including java with some limitations.
