I believe that’s “grudgingly supplied”, not “approved”.   Apple has been trying to get rid of Java 6 for a while now.

I can’t.  The dependency isn’t directly in wget, but its dependency libidn, for which I am not the maintainer.  I believe libidn was deliberately updated to use a more modern Java because Apple hadn’t released Java 6 for High Sierra yet.

I’ve been building stuff on OS X since its beginning, and on Linux for several years before that (i.e. more that 20 years of building on Unix-like systems), so I’m well aware of this.  Our build procedure for wget doesn’t care one bit about Java.

The only reason that libidn has a Java dependency is because its build process builds an accompanying Java plugin.  When installing wget from the binary distribution, which applies to the majority of our users, only the libidn-shlibs library package is required.

Not quite correct. You’re installing the JDK and an accompanying JRE which are independent of the browser plugin JRE.

Fionna:~ hansen$ fink list wget
Scanning package description files..........
Information about 10445 packages read in 1 seconds.
 p   gnu-wget                      [virtual package]

Neither “wget” nor “wget-gnutls” need libidn.  It might be that some other dependency needs Java, though—I haven’t investigated that.

I don’t think anybody is likely to pay me enough for my time to try to roll my own analogue to libidn and port wget to use that.
