Hi All,
I have a Spring-based web application and use a customized Xtext DSL.
I have a Spring bean that will load my DSL using XtextResourceSet during the startup of the application.
Everything is fine when the web application is run under Jetty/Tomcat.
But if I write a unit test that using SpringTestRunner, when initializing this bean, a lot of exceptions are thrown by xtext like the following:

What I don't understand is why these exceptions only happen in JUNIT test and how to resolve it?
