Fix travis errors (#729)

Travis CI is showing the following failure message:

Setting APT mirror in /etc/apt/sources.list: 
http://us-east-1.ec2.archive.ubuntu.com/ubuntu/
oraclejdk10 is deprecated. See 
https://www.oracle.com/technetwork/java/javase/eol-135779.html
for more details. Consider using openjdk10 instead.

Hence removing oraclejdk10 target. Also, fixed failure due to TLS problems.
