A 404 error occurs when using a CryptoMapper

Under certain prerequisites a 404 error occurs.

The prerequisites are:

• A CryptoMapper is used as RequestMapper
• SecuritySettings.enforceMounts is set to true
• Class SomePage is not annotated with @MountPath

Reason:
In BookmarkableMapper.parseRequest (called indirectly by CryptoMapper.mapRequest) the method matches returns false,
as reverseUrl is the encrypted URL (rootRequestMapper is a CryptoMapper) but BookmarkableMapper.matches expects a decrypted URL.

BookmarkableMapper - lines 132 ff.:

Url reverseUrl = application.getRootRequestMapper().mapHandler(
	new RenderPageRequestHandler(new PageProvider(pageClass)));
if (!matches(request.cloneWithUrl(reverseUrl)))
{
	return null;
}

As a result BookmarkableMapper.mapRequest and hence CryptoMapper.mapRequest returns null resulting in a 404 error.
