"Instance Health" detected a Collation problem with the following error message: The session collation of: 'GERMAN' is unsupported by JIRA

Each time JIRA opens a DB session on an Oracle DB the session does not take the nls_* parameters set in the DB or the DB schema but from informations it gets from the OS.
(i.e. set nls_sort=BINARY' on DB and and DB session will be changed within the session to nls_sort=GERMAN' just because the DB is installed on a German Windows2012)

In my opinion the language of the OS must not influence the DB session parameters.

Our selfmade solution is:
Creating a session trigger on the DB which alters the parameter back to nls_sort=BINARY'

Please fix this bug or document it in the installation description.
