> There is a possibility of an overflow at 
> https://github.com/apache/httpcore/blob/4.4.x/httpcore/src/main/java/org/apache/http/pool/PoolEntry.java#L88
>  when calculating the validity deadline. When Long.MAX_VALUE (or values 
> sufficiently close to it) is used as the TTL it results in a negative 
> validity deadline which causes every connection to be single use. This is 
> very surprising behavior and may not be immediately obvious in test 
> environments.
