When first deploying a process with process initiation authorization (<process id="process" name="Process" isExecutable="true" activiti:candidateStarterUsers="user" activiti:candidateStarterGroups="group">), the BpmnDeployer will properly create identity links in ACT_RU_IDENTITYLINK table.
However when the application is redeployed, BpmnDeployer will create the same set of identity links again, without deleting the old ones. The redundant records are never deleted. This happens again and again.
This behavior does not affect any functionality, so it's more of a nuisance than a bug, but hopefully still worth reporting.
