---------------------------------------------------------------------

You are confusing two things: JVM distribution and JVM implementation. {{java.vendor}} points to the entity producing the distribution. If you download Oracle Java, you will see "Oracle Corporation". OpenJDK != Oracle Java.
the Java vendor AdoptOpenJDK provides two distros, one contains HotSpot JVM impl while the other one contains OpenJ9 JVM impl.

>             Project: Maven Enforcer Plugin
>          Issue Type: Improvement
>          Components: Plugin
>    Affects Versions: 3.0.0-M3
>            Reporter: Mark Symons
>            Assignee: Michael Osipov
>            Priority: Major
>             Fix For: 3.0.0-M4

> Include JavaVendor in the output of the {{display-info}} goal.
> This addition would make it much easier to determine whether Oracle or OpenJDK is being used (or which flavour of OpenJDK).  Currently:
> {noformat}
> [INFO] --- maven-enforcer-plugin:3.0.0-M3:display-info (default-cli) @ xxxxx ---
>  [INFO] Maven Version: 3.6.3
>  [INFO] JDK Version: 1.8.0_232 normalized as: 1.8.0-232
>  [INFO] OS Info: Arch: amd64 Family: unix Name: linux Version: 3.10.0-693.21.1.el7.x86_64
> {noformat}
> The JDK here is Zulu OpenJDK...  but one would have  to do some research to know for sure that it could not be Oracle (a no-no in my organisation) where the latest version at time of writing happens to be 1.8.0-221.
> MENFORCER-338 requests that Javavendor be enforceable.  I have voted for that enhancement but log this as something that might (hopefully) be easier to implement in the short term.
> It would also provide the benefit of making it clearer whether one has a problem that requires going to the effort of configuring enforcement.
