A DESCRIPTION OF THE PROBLEM :
The Oracle Help for Java API Reference Release 12c (12.1.3) specifies a viewer class Viewer (java.lang.Object
 > oracle.help.viewer.Viewer). However the reference package does not exist in the release of ohj-12.2.1.0.0. and thus cannot be imported into a Java application.

REGRESSION : Last worked in version 8u251

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In a Java project, add the following compile time libraries:
help-4_2-ehelp-integration.jar
ohj.jar
oracle_ice.jar
share.jar
jewt.jar

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
To be able to create an instance of the Viewer class
ACTUAL -
The import is flagged as "Cannot find symbol; symbol: class viewer; package: oracle.help
