Has anyone seen this weirdness before? (Javadoc generation for JDK 9)
Copy code
:junit-jupiter-api:javadocPicked up _JAVA_OPTIONS: -Xmx500m
javadoc: error - An exception occurred while building a component: TagInfo
	(com.sun.tools.javac.code.ClassFinder$BadClassFile: bad class file: /home/travis/build/junit-team/junit5/junit-jupiter-api/build/classes/kotlin/main/org/junit/jupiter/api/AssertionsKt$sam$Supplier$i$44378ebd.class
  undeclared type variable: T
  Please remove or make sure it appears in the correct subdirectory of the classpath.)
Please file a bug against the javadoc tool via the Java bug reporting page
(<http://bugreport.java.com>) after checking the Bug Database (<http://bugs.java.com>)
for duplicates. Include error messages and the following diagnostic in your report. Thank you.
