Work-around: dont add the pdf backend to asciidoctor task configuration.

Can you share which version of Java and which version of JRuby are being used? There are a known issues with various Java and JRuby combinations on Windows, so the version you use is very important.

jdk1.8.0_121 x64 and JRuby... I didn't install it manually. Will check the logs for the JRuby version.

Can it extracted from here: https://github.com/junit-team/junit5/blob/master/documentation/documentation.gradle ?

Update: jdk1.8.0_144 produces the same error

[sormuras]

According to the build log it's: jruby-complete-9.1.12.0.jar

[sormuras]

Found: https://github.com/jruby/jruby/issues/4745 - seems to match exactly.
How do I upgrade the JRuby version now...

[mojavelinux]

You can set the version of JRuby that Gradle uses with the following configuration:

jruby.execVersion '9.1.13.0'

See http://jruby-gradle.org/base/

[mojavelinux]

Actually, since this build doesn't use the JRuby Gradle plugin, it's just a matter of defining the jruby-complete dependency on the classpath. AsciidoctorJ brings in a default version, but you can override it in the normal way. It's just a library.

[mojavelinux]

buildscript {
    dependencies {
        ...
        classpath 'org.jruby:jruby-complete:9.1.13.0'
    }
}

Thanks Dan!

Solved via https://github.com/junit-team/junit5/commit/82f00c7a82d7aeccb54f1ff29194f7fa5a585766

[sormuras]

Using JRuby 9.1.14, it now fails on Linux. See https://github.com/junit-team/junit5/issues/1099#issuecomment-345517452 or https://github.com/jruby/jruby/issues/4805#issuecomment-346008259

On Windows, I can create the PDF.
