Marshal.load should raise EOFError if the file to load from is empty
--------------------------------------------------------------------
Key: JRUBY-2345
URL: http://jira.codehaus.org/browse/JRUBY-2345
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.1
Environment: Latest JRuby from trunk.
Reporter: Vladimir Sizikov
Assignee: Vladimir Sizikov
Priority: Minor
Fix For: JRuby 1.1.1
The following code:
{noformat}
f = File.new('tmp-file', "w+")
Marshal.load(f)
{noformat}
Produces in MRI:
EOFError: end of file reached
But in JRuby:
IOError: Unexpected end of stream
This leads to the following rubyspec failure:
{noformat}
Marshal::load raises EOFError on loading an empty file FAILED
Expected EOFError but got IOError (Unexpected end of stream)
