Our company is planning to move towards AdoptOpenJdk 11 with Wildfly 10 running on it

Our company is planning to move towards AdoptOpenJdk 11 from Oracle JDK8 with Wildfly 10 running on it. All the code and wildfly server will be same(written and supported by JDK8) and since java is backward compatible, I think that it should work theoretically, but are there any issues that we have to be aware of?

I have migrated from openjdk-8 to openjdk-11.
Steps I follow:
1. Add missing Java dependencies in jdk11
2. Upgrade/remove supported plugins (Need to upgrade ASM to 7.1, cglib or other byte manipulation libs)
3. Change JAVA_OPTIONS related to GC.
4. Wildfly support for java11

More details on libs versions check the link

There are a lot of updates from JDK 8 to JDK 11. I would recommend just moving to AdoptOpenJdk 8 in the short term. Your specific code may be ok, but you also have a huge set of dependencies that may be using something that needs updated. For example, what is your build tool? Gradle needed to be updated because it needed a newer version of ASM. Are you using JAX-RS? Jersey 2.27 doesn't work on Java 11.

JavaEE is in a weird place right now because Oracle basically dumped it on the Eclipse foundation (now called JakartaEE). It will take a little while for it to be sorted out.
