See my second post in the thread, there I also attached a sample wab. As I
mentioned, we detected the issue while using Jersey and trying to expose
REST services hosted in jars under WEB-INF/lib. So I looked at how Jersey
is loading resources (see e.g.
com.sun.jersey.api.core.servlet.WebAppResourceConfig) and used a similar
approach:
1. First get all resource paths of jar(s) under WEB-INF/lib
ServletContext servletContext = ...
Set<String> resourcePaths = servletContext.getResourcePaths("/WEB-INF/lib");
2. Then try loading the stream of each resource:
String resourcePath = resourcePaths.iterator().next();
InputStream inputStream = servletContext.getResourceAsStream(resourcePath);
