Exception in thread "Tarantool connector" java.lang.NoSuchMethodError: java.nio.ByteBuffer.clear()Ljava/nio/ByteBuffer;

Both connector library and my program are built by the same compiler on macos.

Fix NoSuchMethodError when Buffer.clear() is called
43d72df 
Tarantool client uses java.nio.ByteBuffer to represent a payload to be
sent through the network. JDK 9 introduces a number of new methods that
override java.nio.Buffer methods in order to return ByteBuffer instead
of Buffer. Because of overriding, those methods are available in JRE 8
or below but cannot be invoked if the connector is built using JDK 9 or
above using new signatures for methods overridden. To be compatible
with JREs before 9, it possible to cast ByteBuffer to Buffer class
explicitly. As a result, a method will be called which is available in
older versions but it breaks conciseness of the code.

Closes: #215
