Description

This bug surfaces when trying to load a Truetype font with the (100% Ruby) Prawn gem, version 0.4.1. I have been unable to trace the exact event where it happens in the Prawn code, but this is an example:

"prawn.rb"
require 'rubygems'
gem 'prawn', '0.4.1'  
require 'prawn'

Prawn::Document.generate "prawn.pdf" do
  font "#{Prawn::BASEDIR}/data/fonts/DejaVuSans.ttf"  # This is what generates the error
  text "Hello from JRuby"
end

When run in the latest JRuby build as of today:

~/dev% jruby -v
jruby 1.1.7 (ruby 1.8.6 patchlevel 287) (2009-01-28 rev 6586) [i386-java]

~/dev% jruby -S gem list

*** LOCAL GEMS ***

prawn (0.4.1)
prawn-layout (0.1.0)
rake (0.8.3)
rspec (1.1.12)
sources (0.0.1)

~/dev% jruby prawn.rb
RubyArray.java:752:in `eltInternal': java.lang.ArrayIndexOutOfBoundsException: 259
	from Pack.java:1197:in `encode'
	from Pack.java:1494:in `pack'
	from RubyArray.java:3235:in `pack'
...

The code works fine in MRI. Problem is also present in JRuby 1.1.6.

You've already got the case reduced well enough ...

but here's some simple steps to reproduce using trunk prawn:

jruby -S gem install test-spec pdf-reader mocha
git clone git://github.com/sandal/prawn.git
cd prawn
git submodule init
git submodule update
jruby -S spec spec/font_spec.rb

Here I come to save the day! That's how you know mighty mouse is on his way!

Anyway, the patch should fix this bug, Charles's test case is correct. I added another test case to the pack/unpack test. I also had a few Digest spec fixes in my working copy, so they're in there too.

Enjoy

If this doesn't work let me know...

Hoa, if you're using warbler this is probably because your .war file includes an older version of the jruby-complete jar. Try replacing the jar in JRUBY_HOME/lib/ruby/gems/1.8/gems/warbler-0.9.12/lib, clear the tmp/war directory of your app and re-warble. That should do the trick.

To clarify: It's working for me now, so this bug is clearly fixed.

Hoa: try Martjin's suggestion...and we'll have a new Warbler release soon that includes updated JRuby.
