Thank you so much @poddingue for your quick response

@poddingue Any specific reason we have to move to Temurin JDK ? We are using currently openjdk version “1.8.0_332” OpenJDK Runtime Environment (build 1.8.0_332-8u332-ga-1~deb9u1-b09) OpenJDK 64-Bit Server VM (build 25.332-b09, mixed mode)

Temurin is an openjdk built by the Eclipse Foundation (see https://adoptium.net/ ). It’s the most used openjdk version probably.

@mawinter69 Thanks for quick response. One last query, is it not possible by any chance to upgrade our current flavour of java we have installed to 17.x ? i.e openjdk version “1.8.0_332”

We support Temurin JDK, so 17.0.11+9 would be the right choice at the time of writing.
