> Tried to upgrade to guava-16 and started getting these errors from Curator on exit:
> Exception in thread "Thread-1" java.lang.NoSuchMethodError: com.google.common.io.Closeables.closeQuietly(Ljava/io/Closeable;)V
> 	at org.apache.curator.ConnectionState.close(ConnectionState.java:109)
> 	at org.apache.curator.CuratorZookeeperClient.close(CuratorZookeeperClient.java:196)
> 	at org.apache.curator.framework.imps.CuratorFrameworkImpl.close(CuratorFrameworkImpl.java:284)
> 	at com.virident.fmc.service.AbstractService.closeCF(AbstractService.java:199)
> 	at com.virident.fmc.service.AbstractService.shutdown(AbstractService.java:215)
> 	at com.virident.fmc.service.AbstractService.access$000(AbstractService.java:31)
> 	at com.virident.fmc.service.AbstractService$1.run(AbstractService.java:98)

> Investigation shows this code:
>     public void close() throws IOException
>     {
>         log.debug("Closing");
>         Closeables.closeQuietly(ensembleProvider);
> This closeQuietly() method is deprecated as of guava 14, and it gone in guava 16.  The
2-parameter closeQuietly() needs to be called, eg:
>         Closeables.closeQuietly(ensembleProvider, true);
> Curator master source still seems to have this bug.  The 2-parameter closeQuietly is
already be available in guava-14 and the 1-parameter version is marked decorated as deprecated
in that release which should have generated deprecation warnings.
> A visual inspection of the various curator projects shows that this deprecated API is
used in many places.  They all should be corrected to use the 2-parameter Closeables.closeQuietly().
