Unhandled Java exception: java.lang.NullPointerException when calling `exec_update` #1033

Hi!

Using JRuby 9.2.8.0 + ARJDBC 52.3. This works with MRI 2.5 but gives NPE with JRuby.

Any idea what is going on?

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'activerecord', '~>5.2.3'
  platform(:jruby) { gem 'activerecord-jdbcsqlite3-adapter', '~>52.3' }
  platform(:mri) { gem 'sqlite3' }
end

require 'active_record'

ActiveRecord::Base.establish_connection(adapter: "sqlite3", database: ":memory:")
ActiveRecord::Base.connection.create_table('comments') { |t| t.text 'comment', null: false }

comment = 'æøåæøåæøå'

ActiveRecord::Base.connection.exec_update("INSERT INTO comments(comment) VALUES ($1)", 'INSERT', [[nil, comment]])
rs = ActiveRecord::Base.connection.exec_query("SELECT * FROM comments WHERE comment=$1", 'SELECT', [[nil, comment]])
pp rs.to_a
$ chruby ruby-2.5
$ ruby exec_update.rb 
[{"id"=>1, "comment"=>"æøåæøåæøå"}]
$ chruby jruby-9.2.8.0
$ ruby exec_update.rb
