World is moving to jdk11 as minimal requirement.

Eclipse requires jdk11 - https://wiki.eclipse.org/Eclipse/Installation

Sonar requires jdk11 - https://docs.sonarqube.org/latest/requirements/requirements/ (they warning us that our sevntu project is still running under jdk8 and will stop to work very soon)

IDEA requires jdk11 - https://www.jetbrains.com/help/idea/installation-guide.html

You do not need to install Java to run IntelliJ IDEA, because JetBrains Runtime is bundled with the IDE (based on JRE 11). However, to develop Java applications, a standalone JDK is required.

we discussed it at #7281 and waited for Eclipse to move to jdk11
