Unfortunately, many people add a repository with Oracle JDK to their package managers and install the JDK from there, due to some perceived better compatibility and/or extra bug fixes. (And in my experience, this is true for the Java plugin; the "official" plugin seems to work better than the IcedTea plugin.)

A few years ago, Minecraft simply wouldn't run nearly as good on OpenJRE, not even the server - it was several times slower. Not sure how it is today since I've stopped playing around 5 years ago.

JavaFX is difficult to use under OpenJDK. I think it has become a library on Java 11, so at least that's a step in the right direction.

  Yes, it has its own website now. https://openjfx.io/ https://openjfx.io/

Confluence is an example of a piece of software that wouldn't run correctly at all under OpenJDK. Even today on the Atlasian docs, they provide a Docker image of Confluence to evaluate, but if you buy a production license, you are required to build an OracleJRE Docker container (they provide instructions) for production. It's been years and they still can't support OpenJDK ... it makes me wonder what weird proprietary crazy reflection shit they're doing in there.

  Last time I tried to run Jira with OpenJDK, I stumbled upon some encryption algorithm not supported in OpenJDK. I didn't research further. But that was a long time ago, nowadays I bet that OpenJDK will work just as well.

    I ran Jira with OpenJDK 8 on FreeBSD, everything worked fine.

    The encryption algos are not supported with Oracle java either. The stronger algos have a separate licence and needs to be downloaded manually for either java sdk

On ARM openjdk has a lot of issues while oracle jdk/jre runs smoothly. Many apps will just crash under openjdk and if they run are much slower also on intel. It should be easy to benchmark this. It is a reason why we moved to .net core entirely. I have nothing running Java anymore. Shame as I liked Clojure somewhat.
