    • OS:
      linux

      Description

      FULL PRODUCT VERSION :
      java version "9"
      Java(TM) SE Runtime Environment (build 9+181)
      Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

      A DESCRIPTION OF THE PROBLEM :
      Running the Javadoc tool produces an error that seems to be related to the javac compiler, although the code compiles fine.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Install JDK 9+181
      Install Maven 3.5.0

      $ git clone https://github.com/eclipse/jetty.project.git
      $ cd jetty.project
      $ git checkout 3c96cf200b201d26c416df86bafa835a09857a59
      $ mvn clean install -DskipTests
      $ mvn javadoc:javadoc


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Javadoc generation completes successfully.
      ACTUAL -
      Javadoc generation aborted with an error
