Works for me:

[aph@nighthawk ~]$ gcj stacktrace.java --main=stacktrace -g
[aph@nighthawk ~]$ ./a.out
stacktrace.e(stacktrace.java:42)
stacktrace.d(stacktrace.java:38)
stacktrace.c(stacktrace.java:31)
stacktrace.b(stacktrace.java:26)
stacktrace.a(stacktrace.java:19)
stacktrace.main(stacktrace.java:12)

Aren't you just compiling without -g ?  There is no debuginfo.
