Trouble building JDK in debug mode

[Sam']

Sorry to create a new post, I have not managed to reply to the other topic
since I had deactivated the notifications..

I am building the JDK on Mac. I have specified "CONF=DebugNative" with the
case sensitive in the gradle.properties file.

You are speaking about -PCONF, but in the gradle I have specified only
"CONF" since it was written like that in the comment above..

Finally after that, I'm following the steps specified here (
https://wiki.openjdk.java.net/display/OpenJFX/Building+OpenJFX#BuildingOpenJFX-Overlay-JDK8
) in order to deploy my JDK. Afterwards, when launching Netbeans, I cannot
see the local variables of JavaFX source code and debug it properly.
