ADDITIONAL SYSTEM INFORMATION :
I'm using OpenJDK 10.0.2, but there is no matching version that I can select from the release drop-down box.

Specifically, I'm using the package java-10-openjdk-devel-10.0.2.0-lp151.2.3.2.x86_64 on openSUSE Leap 15.1.

A DESCRIPTION OF THE PROBLEM :
The stylesheet.css written by JavaDoc starts with the following line:

@import url('resources/fonts/dejavu.css');

However, the file it tries to include isn't written by JavaDoc. As a result, when serving JavaDoc output on a web server, 404 (not found) errors are logged.

There is a bug report for this problem: JDK-8129828. However, that was marked as a duplicate of 8039305, which is not viewable by the public. There is also JDK-8093199 which seems to describe the same problem, but that was marked as fixed in JDK8 in 2014, so if the problem still exists in JDK10 today then I guess it's a regression.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run JavaDoc, put generated documentation in a directory served by a web server, load generated documentation in a web browser.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No errors.
ACTUAL -
I'm seeing 404 (not found) reported on both the web server and the web browser (Chrome, Inspect > Console).

FREQUENCY : always
