Access to jdk.hotspot.agent classes in Java 9?

Hi, I'm writing some code that makes use of the SA classes under
sun.jvm.hotspot. This compiles and runs fine under Java 8 provided I
include sa-jdi.jar but I've just discovered that these are now classified
as JDK internal API in Java 9. There is no alternative so what should I do?
Thanks,
David

Hi David,

The sun.jvm.hotspot classes have always been a JDK internal API. What
has changed in Java 9 is that the Java Platform Module System now
enforces that restriction. To use these classes you must explicitly
export them when running (and compiling?) your application e.g.

--add-exports=jdk.hotspot.agent/sun.jvm.hotspot=ALL-UNNAMED

You may need to do that for each package you need to access.

HTH.

Ok, thanks, that worked and I can now use them again.

Cheers,
