For the AsciiDoc plugin for IntelliJ I create a custom class loader and then call

AsciidoctorJRuby.Factory.create(classloader)

to create an instance. I do this as the list of JARs is determined at runtime.

The expected behavior to me was that all extensions in META-INF should be registered automatically.

But this was not the case.

I found that JRubyAsciidoctor#processRegistrations() doesn't receive the classloader parameter, and neither do its decendants.

A workaround for this: set the thread's classloader like this:

ClassLoader oldCl = Thread.currentThread().getContextClassLoader();
try {
  Thread.currentThread().setContextClassLoader(classloader);
  return AsciidoctorJRuby.Factory.create(classloader);
} finally {
  Thread.currentThread().setContextClassLoader(oldCl);
}

Please advise if this behavior should be changed.

How could a code change look like? Would the classloader be passed down to the ServiceLoader.load() to be passed as a second parameter (currently only one parameter is passed, so the threads default classloader is used)?
