Hi,
The exception ocuurs when instance_eval is invoked with the non-String 2nd
argument.
Please check my patch.
{code}
require 'pathname'
class InstanceEvalTest
def initialize(file)
instance_eval( "def hello; p 'hello'; end", file , 1)
end
end
InstanceEvalTest.new(File.new($0))
{code}
result:
{code}
$ jruby.bat test/test_cast.rb
