WSDD deployment getting stuck due to race condition in WSDDDeployableItem.

We can observe ExecuteThread: '1' and ExecuteThread: '2' are trying to do WSDDDeployment and got stuck at
java.util.HashMap.get(HashMap.java:346).

More information regarding 'HashMap.get() can cause an infinite loop!'

Servers need to be restarted or application has to be redeployed to complete the deployment.
