Kernel#exec should raise Errno::ENOENT if the program to execute doesn't exist
------------------------------------------------------------------------------
Key: JRUBY-2253
URL: http://jira.codehaus.org/browse/JRUBY-2253
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC2
Environment: JRuby 1.1RC2
Reporter: Vladimir Sizikov
Fix For: JRuby 1.1
Attachments: exec-ex.rb
Kernel#exec behavior for MRI (1.8 and 1.9) is that it raises Errno::ENOENT if
the program to execute doesn't exist.
But for JRuby, the Errno is not being raised.
The attached tests pass with MRI, but fail with JRuby:
1) Failure:
test_exec_empty(ExecTest) [exec-ex.rb:5]:
<Errno::ENOENT> exception expected but was
Class: <SystemExit>
Message: <"exit">
---Backtrace---
exec-ex.rb:5:in `test_exec_empty'
---------------
2) Failure:
test_exec_non_existing(ExecTest) [exec-ex.rb:11]:
<Errno::ENOENT> exception expected but was
Class: <SystemExit>
Message: <"exit">
---Backtrace---
exec-ex.rb:11:in `test_exec_non_existing'
---------------
This also leads to one rubyspec failure:

1)
Kernel#exec raises a SystemCallError if cmd cannot execute FAILED
Expected SystemCallError but got SystemExit (exit):
