JSPM fails with error "Invalid Response Code: (401) Unauthorized"

Hi,

We are unable to start the JSPM in our production PI system. When we go
to /usr/sap/TXP/DVEBMGS50/j2ee/JSPM and execute ./go the JSPM fails
with error "Invalid Response Code: (401) Unauthorized"

I checked the notes 1401712 and 1600846. As per note 1600846 in the
default profile "service/protectedwebmethods = DEFAULT" should be
maintained. But when i checked in our system the value is set as
SDEFAULT and not DEFAULT.(service/protectedwebmethods = SDEFAULT)

Please let us know how we can resolve the JSPM issue as we need to
patch some PI components very soon in the coming weekend.

Thanks,
Sanjiv
