Saxon

This is continuation of https://saxonica.plan.io/boards/3/topics/8459.

While trying to adapt existing code to changed Saxon's API I've updated my code like this:

    configuration.setResourceResolver(
      new ResourceResolverWrappingURIResolver(
        new StandardURIResolver(configuration)
        {
          @Override
          public Source resolve(String href, String base)
            throws XPathException
          {
            if ((href != null) && (base != null) && base.startsWith("classpath:"))
            {
              var uri = new URI(href);
                
              if (!uri.isAbsolute())
              {
                href = "classpath:" + 
                  new URI(base.substring("classpath:".length())).
                  resolve(uri).
                  toString();
              }
            }
            
            return super.resolve(href, base);
          }
        }));

When I run transformation with my custom URI resolver I get StackOverflowError exception:

     [java] Exception in thread "main" java.lang.StackOverflowError
     [java] 	at net.sf.saxon.Configuration.isTiming(Configuration.java:2278)

     [java] 	at ...$2.resolve()
     [java] 	...

In fact I think following code will result in exactly the same error:

    configuration.setResourceResolver(new ResourceResolverWrappingURIResolver(new StandardURIResolver(configuration)));

Error, in my opinion, is due to that configuration calls resolver, and StandardURIResolver calls configuration's resolver.
