Hi All,  
I am using ES 1.4.4. and Java 8. Both running on the same machine.  
Below is the exception when I am trying to insert recored using Java Client.

I'm unsure but it looks like a bug.  
Any chance you can reproduce it with a CURL script?

But first, please update to 1.6 and see if this has been fixed already.

Thank you for quick reply David. This is the first time I am seeing this exception and this is in production and I was not able to reproduce in dev environment. As you suggested I will try to update my ES to 1.6.
