Thanks for the contribution. I am a bit unsure of whether this might be a licensing issue. The Kotlin debug adapter is licensed very permissively whereas JDK implementations might not be. At the very least we may have to retain their license headers.

Thanks for the advice! I'll have a deeper investigation to this and fix the license issue.

@fwcd
The code in SunCommandLineLauncher is GPLv2 and cannot be used in this repo easily.
So I will create a new KDALaunchingConnector which extends org.eclipse.jdi.internal.SocketLaunchingConnectorImpl (EPL License).

This pullreq will be closed. A new pullreq will be added later. Sorry for the inconvenience.
