Ambigous createRequest() in ERXApplication???

Folks,

it may simply be too late after a long day but I cannot understand why Eclipse is having a problem with the following code fragment and what to do to fix it:

This is in Application extends ERXApplication...

	public WORequest createRequest(String aMethod,
			String aURL,
			String anHTTPVersion,
			NSDictionary someHeaders,
			NSData aContent,
			NSDictionary someInfo) {
		if ("OPTIONS".equalsIgnoreCase(aMethod)) {
			System.err.println("Creating fudged request for OPTIONS: URL=" + aURL + ", headers=" + someHeaders);
			return new Request("GET", aURL, anHTTPVersion, someHeaders, aContent, someInfo);
		} else
			return super.createRequest(aMethod, aURL, anHTTPVersion, someHeaders, aContent, someInfo);
	}

The method createRequest(String, String, String, NSDictionary, NSData, NSDictionary) is ambiguous for the type ERXApplication

ERXApplication has two definitions for createRequest() and I think they have different signature. So what the heck am I missing here? Confused!

Thanks
