How to fix Unrecognized VM option 'UseParNewGC'

Hey there.

SonarQube v5.6.7 is extremely old. Why are you trying too install this version instead of the current LTS (v7.9.5) or latest (v8.6) version?

Java 14 was just a dream back in 2016 when SonarQube v5.6 was released :wink: It runs on Java 8 only.
