CachedCoordinator Cache Initialization Blocks a Thread for a Very Long Time (Doc ID 1496472.1)

Symptoms

In case of two phase commit, when a cached coordinator is required e.g. in order to commit a transaction involving another WLS node resource within a cluster, the initialization of the cached remote coordinator stub makes threads always wait for the whole timeout value (20s+). This sometimes causes entire business transactions to roll-back because of transaction time-out.
  
The time lost in processing is 20s+ each time, which precisely is the default value of the weblogic.JTA.ContactCoordinatorWaitSeconds parameter.
