Reported issue is not reproducible in latest Stable/Oxygen build karaf-0.8.3-20180712.031505-267 and latest fluorine build karaf-0.9.0-20180711.125024-1566.

The same behavior is explained with bug submitter(Rajarajan) and bug submitter also agreed that issue is not happening in tested latest builds.

Hence closing this issue.
