Since fd9382d CDT has required Java 11, this change fixes the Javdoc
shipped as part of the doc.isv bundle to link to Java 11 classes
instead of Java 8 classes.
Fixes the following warning seen during the build: "javadoc: warning
The code being documented uses modules but the packages defined in
https://docs.oracle.com/javase/8/docs/api/ are in the unnamed
module."
