i have faced the same issue, for this Java up-grade is not required. Just intall the openssl package and run installation host registration went fine. 1) from vm connect to the internet 2) Install the opnssl package #yum install openssl if it installed fine, you can proceed with host Registration . it worked for me.

For connecting the internet on VM , you have to be in Brigde Network. 1) Check are you able to ping the host from vm ware, reverse dns should be enabled 1) look at default gateway 3) update same ip address for the gateway , use "wget" once work is done ,you can switch to NAT.
