JBoss Fuse Server not releasing port even after stopping bundle

Question

I have deployed 2 bundle. Both are exposing Rest Webservice on port 9001 and 9002. Now when i go to JBoss Fuse installed directly, run karaf.sh which will opne karaf console. I tried to list all bundle and , stop bundle with their bundle id's. However the bundle which is exposing a service on 9001 doesn't close. After stopping both bundle when i run netstat -anp | grep 9001 i "tcp 0 0 ::ffff:172.16.50.31:9001 ::: LISTEN 2511/java" but when i run same command for 9002 it doesnt show any process which means port 9002 was released when i stopped bundle corresponding to it but same didnt happen for 9001. I am doing hot deployment of jar's i.e placing jar into deploy folder of JBoss Fuse.
