Welcome to the community!

It’s not surprising you’re having trouble upgrading your underlying version of Java. It’s been a while, but I don’t think we started supporting Java 8 until the 6 series.

SonarQube 5.5 is nearly 3.5 years old. You’re more than 3 LTSs behind. You should consider upgrading at your earliest convenience to 7.9.1 which is the latest version and the current LTS. Note that your upgrade path will need to be 5.5 -> 5.6.7 -> 6.7.7 -> 7.9.1.

Also, you need to make sure you re-analyze all your projects between 6.7.7 and 7.9.1. There are migrations in 7.9.1 that will fail otherwise.

Good luck!
