Cluster disconnected automatically after open bucket



I am developing a java program that have to communicate with CB server.
Firstly, i built a new project with NetBeans and use Java SDK to connect CB server perfectly.
Secondly, i move all source code and Java SDK from NetBeans to a existing project that built with JBoss. After the first build and run, i saw a warning i have not seen that before in NetBeans. Then it create cluster normally but the connection was disconnected after open a bucket.

My code

cluster = CouchbaseCluster.create("my_ip");
bucket = cluster.openBucket("my_bucket");

Print out

Line 1 is the warning message i mentioned.
Line 2 is config
Line 3 Cluster connected
Line 4 Bucket Opened
Line 5 Cluster disconnected

I guess that warning message is the reason but i don’t know how to fix it.
Thanks for help


Can you please retry with the released 2.1.2 version and see if it fixes your issue? We had a regression in 2.1.1 that was addressed there. If not, let us know here and we’ll check further.
