Uninitialized constant Aws::Client::Errors on jruby-9.0.5.0

[camullen]

When creating and then destroying an object in S3, calling exists? on that object raises a uninitialized constant Aws::Client::Errors error

I've tested the following code on mri 2.2.3 and jruby-9.0.1.0, and it doesn't produce an error. Perhaps its a bug specific to jruby-9.0.5.0 or maybe your const_get call is buggy?

Sample Code To Reproduce Error:

require 'aws-sdk'

def aws_creds
  id = ENV['AWS_ACCESS_KEY_ID']
  secret = ENV['AWS_SECRET_ACCESS_KEY']
  Aws::Credentials.new(id, secret)
end

def aws_region
  ENV['AWS_REGION']
end

def bucket_name
  ENV['S3_BUCKET']
end

Aws.config.update({
  region: aws_region,
  credentials: aws_creds
})

body = 'My test string - should be deleted!'
key = 'test_upload/destroy.txt'

bucket = Aws::S3::Resource.new.bucket(bucket_name)
obj = bucket.object(key)
obj.put(body: body)
bucket.object(key).delete
key_exists = bucket.object(key).exists?

puts "Does key: #{key} exist in bucket: #{bucket_name}?"
puts key_exists

Gemfile:

source 'https://rubygems.org'

ruby '2.2.3', engine: 'jruby', engine_version: '9.0.5.0'
#ruby=jruby-9.0.5.0

gem 'aws-sdk', '2.1.15'

Seems there is a corresponding discussion on the JRuby repo as well. Adding this link for reference.

jruby/jruby#3645

Thanks, the link is helpful for getting some initial context.

@newellista It appears that the linked jruby issue has been resolved. I'm not sure when they plan to release an update, but it doesn't appear the SDK requires any change currently. Please feel free to re-open if needed.
