There's an easy way to check: try it out. There's another one that I like: 
$ perl -Mre=debug -ce '/[a-z-[bc]]/'
Compiling REx "[a-z-[bc]]"
Final program:
   1: ANYOF[\-[a-z][] (12)
  12: EXACT <]> (14)
  14: END (0)
anchored "]" at 1 (checking anchored) stclass ANYOF[\-[a-z][] minlen 2
-e syntax OK
Freeing REx: "[a-z-[bc]]"

It tells you that the final closing square bracket is interpreted as a literal (EXACT) match, so it surely didn't parse the regex class the same way as Java does.

Perl 6 - second systems done right
