Answer 1

Here, it raises a SIGFPE.

You forgot to tell strace to follow children. Add the -f option to strace and you should see something similar to:

[pid  2304] read(3, "\312\376\272\276\0\0\0001\0n\n\0\23\0I\t\0\3\0J\7\0K\n\0L\0M\n\0N\0"..., 2369) = 2369
[pid  2304] --- SIGFPE (Floating point exception) @ 0 (0) ---
[pid  2304] rt_sigreturn(0x1c50800)     = 5
[pid  2304] write(2, "Exception in thread \"main\" ", 27Exception in thread "main" ) = 27
[pid  2304] write(2, "java.lang.ArithmeticException: /"..., 40java.lang.ArithmeticException: / by zero) = 40
[pid  2304] write(2, "\n", 1
