If the mk_jolokia agent plugin was used the HW-/SW Inventory would fail. Therefore the agent plugin could not be used for Windows.

The reason for that was that in Python 3 sys.stdout returns "\r\n" as linebreak for Windows. Checkmk can't handle this therefore we removed it by replacing the default sys.stdout.
