getResource can throw IllegalArgumentException

Browse Source 
Class.getResource, ClassLoader.getResource, and ClassLoader.getSystemResource will throw IllegalArgumentException if a malformed URL is provided to them.

According to its javadoc, resolveURL should return null if not resolvable, so catch the IllegalArgumentException and return null.
