File.executable? displays warning "executable? does not in this environment and 
will return a dummy value"
----------------------------------------------------------------------------------------------------------

                 Key: JRUBY-5139
                 URL: http://jira.codehaus.org/browse/JRUBY-5139
             Project: JRuby
          Issue Type: Bug
          Components: Core Classes/Modules
    Affects Versions: JRuby 1.5.3
         Environment: Mac OS X 10.4 (Intel)
Java 1.5.0_19
Installed through Maven 3.0 as a dependency of cuke4duke
            Reporter: Martin Pain
            Priority: Minor


In Java 5, File.exectuable? displays a warning message "executable? does not in 
this environment and will return a dummy value". I believe this may be linked 
to the limitations of Java 5 as mentioned in [issue 
1348|http://jira.codehaus.org/browse/JRUBY-1348], as so this method presumably 
could have a workaround spawning an external command too.

I hit this error when trying to install 
[cuke4duke|http://github.com/aslakhellesoy/cuke4duke/] from maven. See 
[cuke4duke's issue report on 
github|http://github.com/aslakhellesoy/cuke4duke/issues/#issue/80] for the 
steps I've tried, and also [the output from the 
install|http://pastebin.com/LuFWQpwU].
