__FILE__ is not expanded when it is used from within a a compiled ruby script
used as the main class of an executable jar
-------------------------------------------------------------------------------------------------------------------------
Key: JRUBY-4825
URL: http://jira.codehaus.org/browse/JRUBY-4825
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.5
Environment: Windows XP, Java 1.6, JRuby 1.5 (Encountered on multiple
other configurations)
Reporter: Benjamin Christenson
Assignee: Thomas E Enebo
Priority: Minor
Attachments: fubar.jar
Below is a screen dump of the Windows command line script I used to build and
test the attached jar file.
Notice that when executing the compiled main script directly, __FILE__ returns
the string 'main.rb' rather than 'file:/C:/jruby_test/fubar.jar!/main.class'.
Other cases, such as requiring the same compiled script rather than executing
it directly, produce the expected result.
