JavaDoc for setCollectResponseAsync

Method 'setCollectResponseAsync'
Could expand the javadoc details on what this does - current associated doc with method doesnt go into much detail.
Only if you read the doc associated with 'java.lang.Object k(java.lang.Object x)' does setCollectResponseAsync make sense, as it refers to the other method i.e. "If the caller has already indicated via setCollectResponseAsync that the response message will be read async..."
