/**
* This class models an execution context (transaction, security, etc)
* with which the Work instance must be executed.
* This class is provided as a convenience for easily creating
* ExecutionContext instances by extending this class
* and overriding only those methods of interest.
*
* Some reasons why it is better for ExecutionContext
* to be a class rather than an interface:
*
- There is no need for a resource adapter to implement this class.
* It only needs to implement the context information like
* transaction, etc.
*
- The resource adapter code does not have to change when the
*
ExecutionContext class evolves. For example, more context
* types could be added to the ExecutionContext class
* (in the future) without forcing resource adapter implementations
* to change.
