A DESCRIPTION OF THE PROBLEM :
Javadoc fails for a valid class file that was compiled with javac:

An internal exception has occurred. 
	(com.sun.tools.javac.code.ClassFinder$BadClassFile: bad class file: /Users/dphillips/src/presto/presto-hive/target/presto-hive-0.195-SNAPSHOT.jar(/com/facebook/presto/hive/HiveSplitManager$1.class)
  undeclared type variable: T


REGRESSION.  Last worked in version 8u162

ADDITIONAL REGRESSION INFORMATION: 
java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the following:

git clone https://github.com/prestodb/presto
./mvnw clean install -DskipTests -Dair.check.skip-all -P ci -pl presto-hive-hadoop2 -am

Explanation: Javadoc fails for the "presto-hive-hadoop2" module of the Presto project. You can reproduce by cloning the project and building that module and dependencies. The "ci" profile is needed to run Javadoc. Disabling tests and checkers make the build faster (not required).
