/**
* 17.6.2.1 NotSupported
*
* The Container invokes an enterprise Bean method whose transaction attribute
* is set to NotSupported with an unspecified transaction context.
*
* If a client calls with a transaction context, the container suspends the
* association of the transaction context with the current thread before
* invoking the enterprise bean's business method. The container resumes the
* suspended association when the business method has completed. The suspended
* transaction context of the client is not passed to the resource managers or
* other enterprise Bean objects that are invoked from the business method.
*
* If the business method invokes other enterprise beans, the Container passes
* no transaction context with the invocation.
*
* Refer to Subsection 17.6.5 for more details of how the Container can
* implement this case.
