Since upgrading from 0.19.3 to 0.19.4, I get an exception whenever I  
close an (embedded) elasticsearch instance:

client.admin().indices().prepareFlush("\_all").execute().actionGet();  
client.close();  
node.close();

[warn] n.c.DefaultChannelPipeline - An exception was thrown by an  
exception handler.
