WebSphere Application Server - What the heck is nulldllsdir ?

Not a problem per se, but I noticed references to nulldllsdir in my WAS SystemOut.log file during the startup of an IBM BPM Advanced 8.5.5 environment (running on WAS ND 8.5.5.4 )

This is what I see: -

user.install.root = /opt/IBM/WebSphere/AppServer/profiles/AppSrv01
Java Home = /opt/IBM/WebSphere/AppServer/java/jre
ws.ext.dirs = /opt/IBM/WebSphere/AppServer/java/lib:/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/classes:/opt/IBM/WebSphere/AppS
erver/classes:/opt/IBM/WebSphere/AppServer/lib:/opt/IBM/WebSphere/AppServer/installedChannels:/opt/IBM/WebSphere/AppServer/lib/ext

Java Library path = /opt/IBM/WebSphere/AppServer/lib/native/linux/x86_64/:/opt/IBM/WebSphere/AppServer/java/jre/lib/amd64/compress

usr/lib:
Orb Version = IBM Java ORB build orb626ifx-20140912.00 (IX90155)

Quelle surprise, but this directory doesn't exist.

Looking around, I can see that it's being set within the profile template(s) that are used to set up the cell e.g.

cat /opt/IBM/WebSphere/AppServer/profileTemplates/managed/documents/bin/setupCmdLine.sh |grep -i null
      LIBPATH="$WAS_HOME"/nulldllsdir
      LD_LIBRARY_PATH="$WAS_HOME"/nulldllsdir
      LD_LIBRARY_PATH="$WAS_HOME"/nulldllsdir
      SHLIB_PATH="$WAS_HOME"/nulldllsdir

This is what I have: -

/opt/IBM/InstallationManager/eclipse/tools/imcl listInstalledPackages
com.ibm.cic.agent_1.8.1000.20141126_2002
com.ibm.bpm.ADV.v85_8.5.5000.20140604_1130

com.ibm.websphere.PLG.v85_8.5.5004.20141119_1746

I'll do a clean install of WAS 8.5.5.4 and see whether I get the same .....
