[infinispan-dev] Ant based kill not fully working? Re: ISPN-4567

Hi guys,

Thanks a lot for your feedback on this.

Having looked closer, the log message says:

> [echo] Killing Infinispan server with PID - 3658 29739 

And the pattern of how that log message gets computed is:

> <echo message="Killing Infinispan server with PID - ${pid}”/>

So, according to that, ${pid} is “3658 29739” which looks wrong.

Not sure what that means, whether there are two processes running and both should be killed, or the way the PID is computed is buggy.

InfinispanServerKillProcessor has a slightly different way to compute the PID, maybe it does it correctly? WDYT?
