The Oracle JVM and the OpenJDK JVM (as provided by AdoptOpenJDK and friends) are for all practical purposes identical. There was a time when OpenJDK was still young that you'd probably prefer the Oracle JVM. But since maybe 5-7 years now, the Oracle JVM is basically composed of the OpenJDK plus some additional Oracle licensed features that don't affect many/most applications.

In short, use the OpenJDK for your project. There are no real downsides for 98% of applications. AdoptOpenJDK is a great source, or likewise vendors like Redhat who are also maintaining OpenJDK distributions.
