The 1.1.4 release is the fourth bugfix release for the 1.1 series. It mainly fixes a bug introduced in 1.1.3 that comes up when trying to use it with buckets of type "Memcached".
When using the 1.1.3 release in combination with a bucket of type "memcached", the initial client construction fails with an Exception. This was because of the previously introduced backoff on warmup, which uses the number of vBuckets to determine the warmup state. The problem associated with this enhancement is that "memcached" buckets do not use the concept of vbuckets at all. This has been fixed, warmup is now ignored for those bucket types.
When using the ConnectionFactory during CouchbaseClient initialization, it could happen that some of the properties were not correctly initialized wih default values and this can lead to NPEs when those values get accessed later. Proper default values are now used automatically when not provided otherwise.
