Robert already suggested to use ToolProvider for the JDK9+ builds. I created such a patch for jlink and I could create s similar one for the compiler and javadoc plugin. This would solve the underlying problem from my understanding.
As fork mode and fork count would not apply, I would suggest that the ToolProvider is only used if fork mode is "no fork". This way, existing configurations are not affected. Does that make sense?
