We are getting a RepositoryException with our application. We have a submission that is created with a stand alone java application client (basically a zip file). The code below takes the zip and extracts it into the Alfresco repository.
The create dossier function is run by our submission administrator under their account name. In order to have the sufficient permissions to do all the functions required in the create dossier, the code logs in to the system account using jcr credentials( adminSession = helper.getJcrSession())
We are getting an intermittent problem where the create dossier process throws an exception "Only one active session is allowed per thread."
We have not been able to determine what the cause of the exception is. We have tried removing the code related to logging in as system and it appears to have resolved the issue. We are not sure why it was required to log in as system. This creates and auditing problem as well since all the dossiers/folders/files are created with system as owner/modifier so we lose the ability to track who submitted what.
We are concerned about releasing this to production since we have not been able to say for certain that this problem won't manifest itself elsewhere. We would like to determine the root cause of the exception to be more confident in our fix.
Does anyone have any insight as to why we might get this exception when switching to the system account? Are there other process in alfresco that would be running as system by default as well? (i.e. something like lucene.. do you know how to determine what credentials lucene runs under?)

The error messaage is clear, only one JCR session is allowed per thread.
The issue is why are more than one sessions per thread being created. However it doesn't look like that JCR session is actually used.
