Are you able to read STDOUT/STDERR during execution to get an idea of
what is actually going on?  You might try adding -vvv -d3 to the
execution to get more detailed output.

My Java is _very_ rusty but in perl this would look something like:

open(NMAP, "nmap -d3 -vvv [commands] 2>&1 |") or die "Could not execute Nmap: $!\n";
