ClassLoader getResource(...) does not check WEB-INF/lib JARs

[andymc12]

Issue Overview

When my test app calls getResource("META-INF/someResource.txt") on the web app's classloader, it fails to find anything - even though the file exists in a JAR file in the WEB-INF/lib directory. When I search for the same resource using getResources, the returned set of URLs includes the URL to the resource in the WEB-INF/lib JAR file.

Expected Behaviour

The getResource method should search JAR files in the WEB-INF/lib directory after searching the WEB-INF/classes directory.

Current Behaviour

The getResource method only searches the WEB-INF/classes directory.

Steps To Reproduce

1. Deploy a WAR file that contains a WEB-INF/lib JAR file that contains a text files called META-INF/someResource.txt.
2. From another test case, obtain the WAR's classloader and invoke loader.getResources("META-INF/someResource.txt") - this will return an Enumeration with a URL to the resource - all good so far.
3. From another test case, obtain the WAR's classloader and invoke loader.getResource("META-INF/someResource.txt") - this will fail.

Additional Information

I think the problem is here:

arquillian-container-weld/impl/src/main/java/org/jboss/arquillian/container/weld/embedded/WebArchiveClassLoader.java

Line 74 in 96b67cb

public URL findResource(String name) {

Unlike the getResources method, this method just adjusts the name for searching the WEB-INF/classes directory and then delegates to the super class. I think it should follow the same pattern as getResources and search the JAR files in the WEB-INF/lib directory.
