In Version 1, the MQeFields structure passed to the MQeQueueManager
allowed the specification of the following two aliases:
- (ascii)AttributeKey_2=com.ibm.mqe.attributes.MQeSharedKey
- (ascii)AttributeKey_1=com.ibm.mqe.MQeKey
Those aliases specified the default class names to use when loading attribute
keys, where an attribute key class was not specified.
These values are hard-coded in the Version 2.0 and 2.0.1 codebase, and
cannot be changed using the alias mechanism. If the values are specified in
.ini files, or calls to the MQeQueueManager, they are ignored.
