Read resource from "Plug-in from existing JAR archives" [message #990653]

I need Docx4j library in my RCP application.
So i create a new "Plug-in from existing JAR archives" and put all needed JARs there.

But when I use it, I have an error:

ERROR org.docx4j.utils.ResourceUtils .getResource line 40 - Couldn't get resource: org/docx4j/convert/out/pdf/viaXSLFO/docx2fo.xslt

Here the Docx4j source code line:

ClassLoader loader = Thread.currentThread().getContextClassLoader();
if (loader == null) {  // IKVM (v.0.44.0.5) doesn't set context classloader 
  loader = ResourceUtils.class.getClassLoader();
}

How can I allow docx4j JAR to read its resources?
(obviously in my 'docx4j plugin' org/docx4j/convert/out/pdf/viaXSLFO/docx2fo.xslt exists)

Thank you!

Sorry. Here the complete source code:

public static java.io.InputStream  getResource(String filename) throws java.io.IOException
    {
        // Try to load resource from jar.
        ClassLoader loader = Thread.currentThread().getContextClassLoader();
        if (loader == null) {  // IKVM (v.0.44.0.5) doesn't set context classloader 
            loader = ResourceUtils.class.getClassLoader();
        }

        java.net.URL url = loader.getResource(filename);
                
        if (url == null) {
        	log.error("Couldn't get resource: " + filename);
        }

        // Get the jar file
//      JarURLConnection conn = (JarURLConnection) url.openConnection();

        java.io.InputStream is = url.openConnection().getInputStream();

        return is;
    }

BTW, the matter is: I don't want to change source code, so how can I let the "plugin from jar" to find its resources?
