I re-opened the JRUBY-4820 to make sure we don't lose it and based on comments it makes me wonder if it has ever fully been fixed or not. It is a really basic method but File.stat(file) probably uses 'stat' and File.size might use 'fstat' which could be some weird posix compat issue on Windows for us (since I have not looked at these methods in quite a while I will need to revisit this). Worst case we can special case windows and use the jnr-posix method we know works for Windows. Best case we solve what is wrong in jnr-posix to properly support this.
The 20047 error is an interesting error because it still would have been a bug for you. I am assuming foo.txt exists when you ran that. So it should have worked...but didn't...then returned a nonsense error instead of the error of a ENOENT. So if you can somehow squeeze in a third bug into this single call it will be a trifecta :( Color us embarrassed.... -Tom PS- JRUBY-6136 is a difficult issue to solve in my mind. jnr-posix is supposed to expose posix methods and we want proper granularity of errno values. If we mask all the various windows errnos we will gain more cross-platform consistency at the cost that consumers of jnr-posix (jruby is not the only user of it) will lose the specific errnos (who am I to say knowing a mapped network drive errno is not what someone wants). At this point we should capture the two weird errnos we know about on the JRuby side as an interim solution and remap them to ENOENT.
