Description

On WAS, one of the ExtClassCloader returns a null instead of an empty array when getUrls is called.

The following is the list of classloaders in order:
com.ibm.ws.classloader.CompoundClassLoader Delegation Mode: PARENT_FIRST
com.ibm.ws.classloader.JarClassLoader Delegation mode: PARENT_LAST
com.ibm.ws.classloader.ProtectionClassLoader
com.ibm.ws.bootstrap.ExtClassLoader

The following code should fix the issue. setupClasspath method line 402:

if (tcl instanceof URLClassLoader) {
URL[] urls = ((URLClassLoader)tcl).getURLs();
if (urls != null) {
for (URL url : urls) {
if (url.getProtocol().startsWith("file")) {
File file;
try

{ file = new File(url.toURI().getPath()); }

catch (URISyntaxException urise)

{ file = new File(url.getPath()); }

if (file.exists()) {
classPath.append(file.getAbsolutePath())
.append(System
.getProperty("path.separator"));

if (file.getName().endsWith(".jar"))

{ addClasspathFromManifest(classPath, file); }

}
}
}
}
}
