-------------------------------------------------
Key: JRUBY-2806
URL: http://jira.codehaus.org/browse/JRUBY-2806
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.1.3
Reporter: Peter K Chan
Assignee: Thomas E Enebo
Using JRuby revision 7174 (July 15), when compiling some version of
ActiveRecord ahead of time and loading it at runtime from a JAR, sometimes a
collision warning is generated:
{quote}
WARNING: while creating new bindings, found an existing binding; likely a
collision:

The warning happens occasionally but the application seems to functional
normally with no ill effect. For reference purpose, here is the method
definition from that version of the file:
{noformat}
def self.string_to_time(string)
return string unless string.is_a?(String)
time_hash = Date._parse(string)
#rest of code skipped...
{noformat}
