require_relative fails sometimes with JRuby 1.7.22 on Win7

[robertpanzer]

We've got an issue with AsciidoctorJ with asciidoctor-diagram running on Win 7 when JRuby 1.7.22 is used. When asciidoctor-diagram is required the JRuby fails with this:

org.jruby.exceptions.RaiseException: (Errno::ENOENT) C:\Users\robert.panzer\.gradle\caches\modules-2\files-2.1\org.asciidoctor\asciidoctorj-diagram\1.3.1\2bab2cb40a6770e8943c5d944d5961d1b4a6f7e8\asciidoctorj-diagram-.3.1.jar!\gems\asciidoctor-diagram-1.3.1\lib\asciidoctor-diagram\blockdiag.rb

This error does not appear when using the JRuby 1.7.21 or below.

We opened an issue in AsciidoctorJ for that which we resolved atm by downgrading to 1.7.21: https://github.com/asciidoctor/asciidoctorj/issues/401

As there are many, many invocations of require_relative all over the Ruby code, I guess that it is not easy to reproduce this problem with a trivial test program (at least not if you don't know the reason for the error).

I created a small gradle build that reproduces the error:

repositories {
    jcenter()
}

configurations {
    run
}

dependencies {
    run 'org.asciidoctor:asciidoctorj:1.5.3.2'
    run 'org.asciidoctor:asciidoctorj-diagram:1.3.1'
    run 'org.jruby:jruby-complete:1.7.22'
}

task createTestDoc << {
    new File('test.adoc').text = '''= Test document

Test''' 
}

task runTest(type: JavaExec, dependsOn: createTestDoc) {
    classpath = configurations.run
    main = 'org.asciidoctor.cli.AsciidoctorInvoker'
    args '-r', 'asciidoctor-diagram', 'test.adoc'
}

Running gradle rT will produce the error mentioned above. Setting the jruby version to 1.7.21 will successfully render the document.

this will be fixed with jruby-1.7.23 releasing this week.

I backported all the patches from master to jruby-1_7 but did not test this gradle script on windows.

[robertpanzer]

Is it possible to get a snapshot build of 1.7.23-SNAPSHOT so that I could try that?

I tried to run it on my windows VM but it died while I was away from the laptop

[mkristian]

finally got it to work after using an VPN in the US :)

fixed.
