Hello,

I encountered an issue with elasticseach transport client. When executing the close method i received the following exception:

Caused by: com.google.common.util.concurrent.ExecutionError: java.lang.OutOfMemoryError: GC overhead limit exceeded  
at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2201)

After debugging, i see that the method goes in infinite loop.

I note that i am using elasticsearch 2.4.1 with elasticsearch client provided by servicemix: org.apache.servicemix.bundles.elasticsearch: 2.3.5\_1.

The code is the following:

{  
TransportClient client = null;  
try {  
Settings settings = Settings.settingsBuilder()  
.put("[cluster.name](http://cluster.name)", cluster).build();  
client = TransportClient.builder().settings(settings).build();  
client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(host), port))  
//...  
} catch (NoNodeAvailableException e) {  
//.......  
} catch (Exception e) {  
//.......  
} finally {  
if (client != null) {  
client.close();  
}  
}  
}
