Prawn gem nil:NilClass error that doesn't occur in MRI
------------------------------------------------------
Key: JRUBY-3579
URL: http://jira.codehaus.org/browse/JRUBY-3579
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.2
Environment: Windows XP SP3, JRuby 1.2.0, RubyGems 1.3.1, Prawn 0.4.1
Reporter: Brandon Hauff
Assignee: Thomas E Enebo
Fix For: JRuby 1.2
I am using the Prawn gem to create some PDFs. When trying to embed a font I
get an error with JRuby that does not occur with MRI. The simplest case to
reproduce this is shown below:
require 'rubygems'
gem 'prawn'
require 'prawn'
Prawn::Document.generate("test.pdf") do
font "#{Prawn::BASEDIR}/data/fonts/DejaVuSans.ttf"
text "This is a test!!!"
end
In MRI this worked fine. In JRuby 1.2.0 I got the following error:
C:/jruby-1.2.0/lib/ruby/gems/1.8/gems/prawn-0.4.1/lib/prawn/font/ttf.rb:259:in
