Hi Alan,
What exactly do you mean by 'stopped working'? Does your code execution
hang? If so did you take a thread dump? Did it work as a service until you
add -Xrs or is this the first time you ran it as a service? A common trap
when using Runtime.exec etc. is not draining the processes STDERR/STDOUT
streams in separate threads. Failing to do so can result in random
deadlocking during process execution. Here's an example of a way to deal
with that issue [1].
