usually I use loop i over `seq XYZ` and sleep increasing amount (I start sleep with 0.1s then 0.2s then 0.3 ...) then give up
and there is no initial wait
bash -c "for i in `seq 1000 100000 1000`; do echo '' | nc localhost $PORT 1>/dev/null 2>/dev/null && echo $PORT is up && break; usleep $i; done"

When would you even call that? Somehow your Java app needs to report
when it finished setting up its listening socket. You cannot script
around that fact.
