Pathname object in $LOAD_PATH causes error (1.7.14) #1936
Description
Since 1.7.14, require throws TypeError when $LOAD_PATH includes Pathname object. I ran into this error while running some legacy code after upgrading JRuby.
> echo 'puts :a' > a.rb
> rvm use jruby-1.7.13
> ruby -rpathname -e '$LOAD_PATH.unshift Pathname.new("."); require "a"'
a
> rvm use jruby-1.7.14
> ruby -rpathname -e '$LOAD_PATH.unshift Pathname.new("."); require "a"'
TypeError: can't convert Pathname into String
