/**
* This method is used to obtain an instance of the provider specific class that implements the PolicyConfiguration
* interface that corresponds to the identified policy context within the provider. The methods of the
* PolicyConfiguration interface are used to define the policy statements of the identified policy context.
*
* If at the time of the call, the identified policy context does not exist in the provider, then the policy context
* will be created in the provider and the Object that implements the context's PolicyConfiguration Interface will be
* returned. If the state of the identified context is "deleted" or "inService" it will be transitioned to the "open"
* state as a result of the call. The states in the lifecycle of a policy context are defined by the PolicyConfiguration
* interface.
*
* For a given value of policy context identifier, this method must always return the same instance of
* PolicyConfiguration and there must be at most one actual instance of a PolicyConfiguration with a given policy
* context identifier (during a process context).
*
* To preserve the invariant that there be at most one PolicyConfiguration object for a given policy context, it may be
* necessary for this method to be thread safe.
*
*
* @param contextID A String identifying the policy context whose PolicyConfiguration interface is to be returned. The
* value passed to this parameter must not be null.
*
* @param remove A boolean value that establishes whether or not the policy statements of an existing policy context are
* to be removed before its PolicyConfiguration object is returned. If the value passed to this parameter is true, the
* policy statements of an existing policy context will be removed. If the value is false, they will not be removed.
*
* @return an Object that implements the PolicyConfiguration Interface matched to the Policy provider and corresponding
* to the identified policy context.
*
* @throws java.lang.SecurityException when called by an AccessControlContext that has not been granted the "setPolicy"
* SecurityPermission.
*
* @throws javax.security.jacc.PolicyContextException if the implementation throws a checked exception that has not been
* accounted for by the getPolicyConfiguration method signature. The exception thrown by the implementation class will
* be encapsulated (during construction) in the thrown PolicyContextException.
