Connecting to Couchbase over SSL is not getting establish

I have upgraded the version of couchbase sdk 2.5.0 to 2.5.8 earlier it was using ssl connection and which was working fine. But now it is not setting
keystroke file and keystore password and check into java-client jar file and in DefaultCouchbaseEnvironment and found missing this method.
And I am using spring mvc and spring couchbase jar file.
Would you let me know how to set SSL connection?
couchbase version 2.5.8
