david radley commented on FLINK-21672:
--------------------------------------
Thanks [~martijnvisser] - It looks like there is only this reference to
sun.management in the code. I do see that there are references to
_com.sun.management_ classes, for example
[https://github.com/apache/flink/blob/620e5975985944a02886b82362a2bc1774c733e3/flink-runtime/src/main/java/org/apache/flink/runtime/util/EnvironmentInformation.java#L369]
It would be great if we could remove these, but my worry is that there may not
be a vendor neutral way of exercising this capability.
> End to end tests (streaming) aren't Java vendor neutral (sun.management bean

> Hi everyone, have been looking to run the tests for Flink using an 11

> my guess is that AdoptOpenJDK's class-library simply doesn't have this
> package and we should use a more neutral one if that's available - I went
> with
> [https://adoptopenjdk.net/releases.html?variant=openjdk11&jvmVariant=openj9]
> personally (OpenJ9 being the name for IBM's open-sourced J9 JVM), but I
> wonder if that has its own platform specific bean as well; I haven't worked
> on IBM's distribution of Java for almost seven years* but hopefully someone
> may have more insight so you don't need to be using OpenJDK backed by HotSpot
> to run said tests. It would be helpful if we didn't need an (if vendor == IBM
> do this || vendor == Oracle do this ... etc) statement, so you can run the
> tests no matter where you're getting Java from.
>
> *full disclaimer, I work at IBM and helped create AdoptOpenJDK, and used to
> work in its Java team...I've honestly forgot if we have a vendor-neutral bean
> available and now work on something totally different!
> Cheers!
