pool_connection.zk.reopen not working with JRuby

[raphaelhetzel]

Hi,
i'm trying to reopen a connection from a pool in case of a ZK::Exceptions::ConnectionLoss error like described in #92.

I assume that i have to call reopen on connection.zk when using the pool.with_lock { |connection| } method.

However, this does not work with JRuby. Is this an issue with the gem or am i doing something wrong here?

require "bundler/inline"

gemfile true do
  source "https://rubygems.org" do
    gem "zk", "1.9.6"
  end
end
require "zk"

pool = ZK::Pool::Bounded.new(
  "127.0.0.1:2181",
  chroot:      "/test",
  timeout:     1,
  min_clients: 1,
  max_clients: 2
)

opts = { wait: 1 }

pool.with_lock("1234", opts) do |connection|
    puts connection.zk.connected?
    connection.zk.close!
    puts connection.zk.connected?
    puts connection.zk.reopen.inspect
    puts connection.zk.connected?
end

JRuby 9.1.12.0:

true
false
:connecting
false

Waiting longer for the client to be connected yields the same result.

MRI 2.3.3:

true
false
:connected
true
