Classpath resources with Nashorn (JJS)

I don't really know if this belongs here, I couldn't find much
documentation on this issue.
I've noticed that, when using nashorn's command line utility JJS,
any resource that is included in the classpath, be it included in a JAR
or located in a classpath folder, is not available to scripts. A simple
|echo "java.lang.Class.class.getResourceAsStream('/test.txt')"|jjs -cp .|
When a file "test.txt" is included in the current folder (which is
added to the classpath via the -cp option), this code always returns
"null". If I run a similar example using java and the jvm directly I get
the expected resource (an input stream reference). Under rhino I get the
same results, using a similar example.
Is this the expected behavior? Is there a way to access resources
under the classpath in nashorn? This is causing a lot of problems with
spring contexts for example, everytime I try to load my app context from
an XML file I get problems because it cannot find some needed resources
at runtime. This worked fine under rhino, but we are planning on
migrating to nashorn.
I found this github wiki, were it states loading resources is only
possible for nashorn's app class loader:
This related question is given a useful answer, but it involves creating
the nashorn engine programatically, instead of using JJS:
Any help is greatly appreciated.
