IllegalArgumentException:name

Question

Hi
I am using jetty 6_1_8 for creating a Http Server Adapter. I am able to access it in linux but I am getting the following exception in windows
java.lang.IllegalArgumentException: name
     at sun.misc.URLClassPath$Loader.findResource(URLClassPath.java:458)
     at sun.misc.URLClassPath.findResource(URLClassPath.java:145)
     at java.net.URLClassLoader$2.run(URLClassLoader.java:362)
     at java.security.AccessController.doPrivileged(Native Method)
     at java.net.URLClassLoader.findResource(URLClassLoader.java:359)
     at java.lang.ClassLoader.getResource(ClassLoader.java:978)
     at org.mortbay.jetty.webapp.WebAppClassLoader.getResource(WebAppClassLoader.java:258)
     at org.mortbay.resource.Resource.newSystemResource(Resource.java:202)I saw jetty code and it is like
_parent.getResource(name);
name is the location of webdefault.xml which is (E:\DEV_E\install_524_mssql_2008\install\noapp\etc\webdefault.xml) for windows
and for windows it is /ais_local/share/alodha/52/gis_CATA_5241_18000/platform_core/install/noapp/etc/webdefault.xml
I want to understand why it is throwing illegalArgumentException:name?
Also when I dont use this custom webdefault.xml (using jetty provided default webdefault.xml) then it works fine.

I want to know why and when ClassLoader.getResource(name) can give this exception.
The below is the code for URLClassLoader which throws the exception. I just want to understand in what conditions it can throw MalformedURLException which ultimately throws IllegalArgumentException:name
Resource getResource(final String name, boolean check) {
                final URL url;
                try {
                    url = new URL(base, ParseUtil.encodePath(name, false));
                } catch (MalformedURLException e) {
                    throw new IllegalArgumentException("name");
               }
