If in the code, more than one output listener is added to hostshell (hostShell.addOutputListener), you would get  java.lang.IllegalThreadStateException.

It seems in standard error's AbstractHostShellOutputReader, it does
not return the correct value for isAlive(). When the thread is already started,
isAlive() still returns false and which results :
