Kernel.sprintf with argument of some non-standard type doesn't invoke to_int on
it
----------------------------------------------------------------------------------
Key: JRUBY-1738
URL: http://jira.codehaus.org/browse/JRUBY-1738
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: JRuby 1.1b1 from trunk
Reporter: Vladimir Sizikov
Attachments: kernel-sprintf-handling-nonstandard-types.patch
Consider the following:
{noformat}
obj = Object.new
def obj.to_int() 4 end
puts sprintf('%d', obj)
{noformat}
Ruby 1.8.6, Rubinius, Ruby 1.9 return:
4
JRuby:
can't convert #<Class:01x4c47db> into Integer (TypeError)
This leads to numerous Rubinius spec failures for String.
The proposed patch fixes the problem, and adds a unit test.
