The child process can get ist own PID and print it on startup: ManagementFactory.getRuntimeMXBean().getName()
This returns an undefined name of the virtzual machine, but in windows and all UNIX it contains the PID. Looks like pid@localhost. But this is enough to prevent user error when killing and signaling JVMs. ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: [email protected] > -----Original Message----- > From: [email protected] [mailto:[email protected]] On Behalf > Of Dawid Weiss > Sent: Friday, December 07, 2012 2:03 PM > To: [email protected] > Subject: Re: [JENKINS] Lucene-Solr-4.x-Linux (32bit/jdk1.6.0_37) - Build # > 3089 - Failure! > > > The PID of the own Java process can be retrieved from the child by the > > javax.Management API!
