openjdk 9 in ios - any sample xcode project or any sample using JavaLauncher interface?

[Grigory Ptashko]

Hello Bob.


I see. That’s a very useful sample. Thank you very much.

But before I get started may I ask you what are the *.jimage files are?
I see there are no rt.jar or tools.jar anymore.

I’m a long time jdk7 user so I’m not aware of the latest innovations in jdk..

Maybe some documentation links?

Thank you.
