eb.close() hangs for about 1 minute

Reproduce Steps

• Server Side

cd java
mvn clean install -DcreateAssembly=true
java -jar target/python-eventbus-example-3.8.5-jar-with-dependencies.jar -p 7000

• Client side

In Python 3.7 console:

pip install -i https://test.pypi.org/simple/ vertx-eventbus-python==3.8.5a8

>>> from Vertx.eventbus import Eventbus
>>> eb = Eventbus()
>>> eb.state
<State.OPEN: 1>
>>> body={'msg':'hi'}
>>> eb.send('echo',body)
>>> eb.close()   ## HERE it hangs about 1 minute
>>> eb.state
<State.CLOSED: 3>
>>> eb.open()    ## HERE eb.open() failed, may needs a new sokcet?
Traceback (most recent call last):
  File "/home/lgao/anaconda3/lib/python3.7/site-packages/Vertx/eventbus.py", line 226, in open
    self._connect()
  File "/home/lgao/anaconda3/lib/python3.7/site-packages/Vertx/eventbus.py", line 238, in _connect
    self.sock.connect((self.host, self.port))
OSError: [Errno 9] Bad file descriptor

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/lgao/anaconda3/lib/python3.7/site-packages/Vertx/eventbus.py", line 230, in open
    self.close()
  File "/home/lgao/anaconda3/lib/python3.7/site-packages/Vertx/eventbus.py", line 406, in close
    self.wait(State.CLOSED,timeOut=self.timeOut)
  File "/home/lgao/anaconda3/lib/python3.7/site-packages/Vertx/eventbus.py", line 258, in wait
    raise Exception("wait for %s timedOut after %.3f secs" % (state.name,timeOut))
Exception: wait for CLOSED timedOut after 60.000 secs

The eb.close() hangs for about 1 minute, and eb.open() afterwards throws above exception.
