I had the same problem yesterday. On my RHEL-7 installs it came down to an older version of IBM java being installed (Not sure why, it's a test system so has all sorts of stuff on it). I grabbed the latest 1.8_171 and installed that separately then set JAVA_HOME to run it rather than the system default one.

Same here. But the issue was resolved when I explicitly downloaded java 8 instead of using

sudo apt-get install java-default

Thank you. i could install with java version 8.
