Kernel#exec should return subprocess exit value and immediately bubble out of
caller
------------------------------------------------------------------------------------
Key: JRUBY-1988
URL: http://jira.codehaus.org/browse/JRUBY-1988
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Reporter: Charles Oliver Nutter
Assignee: Charles Oliver Nutter
Fix For: JRuby 1.1RC2
Kernel#exec normally replaces the current process with the subprocess. In our
case, that's not yet possible (or not advisable), so we need to spin up the
subprocess, return its exit code, and then exit the calling JRuby "process".
The current code continues executing after exec returns, and if the subprocess
returns a nonzero exit code it throws ENOENT.
Fix coming.
