Root cause was jvisualvm user directory pointing to some old java reference which I deleted and corrected. Details as follows:

In order to find out the details of the issue; I ran jvisualvm with console option

**./jvisualvm -J-Dnetbeans.logger.console=true

Which gave me some output and details as shown below:

-----------------------------------------------------------

Everything was fine in terms of jdk8 and home etc. but user directory was pointing to some non existing java path and then I traced it in my linux filesystem:

User Directory          = /root/.visualvm/7u60

In order to solve the problem; I deleted the /root/.visualvm/7u60 directory in my OS. Ran the ./jvisualvm again and it worked without issue.

Earlier I tried running with ./jvisualvm with --help option where seen the jdkhome and tried for changing the jdkhome but was no luck. Finally removing the folder from the OS worked for me.

Wow! Great!!
