Description

When running the javadoc goal I am getting a NullPointerException back. Unfortunately, the maven plugin does not provide me with enough information to figure out what command-line is being passed to the external javadoc tool, so I am unable to report this bug to Oracle.

Here is the debug output from Maven:

As you can see, I am being told the command-line is: "C:\Program Files\Java\jdk1.8.0_121\jre\..\bin\javadoc.exe" @options @argfile which isn't helpful.

Can you please improve the output so I can figure out the contents behind @options and @argfile?
