Input needed (Tycho & OSGi vs Maven)!

[Isuru Perera]

Hi,

I think that the option #4 is good. It'll look artificial to non-OSGi
programs, but that's just the name. It's better to have FQN for OSGi
programs. As a developer, I know that these artifacts are mainly used by
the JMC tool, based on an OSGi framework. I do not mind the artifact id in
non-OSGi programs as long as I can get the dependencies from the Maven
Central and use JMC core libraries to consume JFR APIs.

Currently, I'm getting the artifacts from local JDK path (
https://github.com/chrishantha/jfr-flame-graph/blob/d563550dcb2b3d87ee78524ff01d712102f8c6d0/gradle/missioncontrol.gradle)
and I could avoid this workaround if the JMC core libraries are available
in Maven Central.

Thank you.
