Overall Satisfaction with OpenJDK

Back in 2018, when the news was being spread around about the coming changes to the JDK license from Oracle, my company back then, naturally, as a software provider, had a minor panic. We were deploying lots of software for our clients, written using Java. I guess it was the final push for us to embrace open source fully. And we went with OpenJDK for our development & deployment needs.
  • It's a JDK, following Java specs.
  • It's free & open source.
  • Can be deployed on servers without licensing.
  • Could be more popular.
  • Free
  • Open source
  • Permissive license
  • Save cost on developer laptops.
  • Save cost on company servers.
  • Save cost on clients' servers.
Obviously, OpenJDK has a more permissive license than Oracle's JDK. Still, Amazon Corretto comes with commercial support, & since it's backed by Amazon's infrastructure, downloading a new package to install on a new laptop/system is just a breeze.

Actually, from a software engineer's point of view, JDK is nothing fancy to think of / talk about. It's just there & it works. Until he/she has to set up a project from scratch, together with the build tool, a JDK has to be chosen. Also, when doing deployment work, having a reliable, readily available JDK to install to target systems is a blessing. Still, Oracle could have done a better job supporting OpenJDK, especially for commercial usage.
