GroovyClassLoader fails to resolve .groovy files in classpath on win32

in GroovyClassLoader#expandClassPath the ClassLoader will try to expand the absolute path from C:\ to \C:\ on win32.

Here's the fix:

private void expandClassPath(List pathList, String base, String classpath) {
paths = classpath.split(File.pathSeparator);
for (int i = 0; i < paths.length; i++) {
File path = null;

if ("".equals(base))

{ path = new File(paths[i]); }

else

{ path = new File(base, paths[i]); }

if (path.exists()) {
if (!path.isDirectory()) {
try

{ // Get the manifest classpath entry from the jar JarFile jar = new JarFile(path); pathList.add(paths[i]); Manifest manifest = jar.getManifest(); Attributes classPathAttributes = manifest.getMainAttributes(); String manifestClassPath = classPathAttributes.getValue("Class-Path"); if (manifestClassPath != null) expandClassPath(pathList, paths[i], manifestClassPath); }

catch (IOException e)

{ // Bad jar, ignore continue; }

} else

{ pathList.add(paths[i]); }

}
}
}

Sorry, I don't know how to create a real diff. This also includes an NPE fix whenever a jar file is missing a Class-Path manifest entry we are not going to try to expand the classpath.
