IO#write breaks JRuby when writing object with special to_s implementation
--------------------------------------------------------------------------
Key: JRUBY-2044
URL: http://jira.codehaus.org/browse/JRUBY-2044
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC1
Environment: Latest Jruby 1.1RC1
Reporter: Vladimir Sizikov
Consider the example:
{noformat}
file = File.open("/tmp/bbb", "w+")
obj = Object.new
def obj.to_s; nil; end
file.write(obj)
{noformat}
MRI handles this just fine.
JRuby breaks with java exception
Also, this happens when running rubyspecs, so it's important to fix.
And the fix is coming.
Exception in thread "main" java.lang.ClassCastException: org.jruby.RubyNil
cannot be cast to org.jruby.RubyString
