Cannot access file contained in a deployment as a regular file in JBoss EAP 5 (Virtual File System / VFS)

Issue

• A FileNotFoundException is thrown when trying to read a file from an archive. After finding the file location via the classloader, an attempt is made to open it as a java.io.File. So, consider a test.properties file in a /config directory in a war. The following will not work to load the properties:

URL configFilesBaseURL = Thread.currentThread().getContextClassLoader().getResource("/config");
String configFilesBaseLocation = configFilesBaseURL.getFile();
File configProp = new File(configFilesBaseLocation + "test.properties");
Properties props = new Properties();
if (configProp != null) {
    props.load(new FileInputStream(configProp));
}

• Jboss EAP 4.3 to 5.1 issues with properties loading.
