Hi Waclaw,
Interesting question, Unfortunately, your assumption is flawed. Reluctant quantifiers in Java work differently - see:
http://docs.oracle.com/javase/tutorial/essential/regex/quant.html <
http://docs.oracle.com/javase/tutorial/essential/regex/quant.html>
TL;DR: Our regex says “find a match of a largest substring with one or more non-slash chars, by starting with an empty string and adding one character at a time until you cannot add another matching character”, i.e. match reluctantly. It does not however mean “find a smallest matching substring and finish”…
Cheers,
Marek

This seems wrong. I assume what you mean is "one or more non-slash characters"; what the above says, is "one or more non-slash characters, but as few as possible"---effectively, just one non-slash character. Didn't you mean "[^/]+"?
