Kathey Marsden commented on DERBY-5582:
---------------------------------------
Thank you Kristian for looking at the patch. That is correct regarding the
condition. We want the main thread to be able to make the original thread
created in main to be in the privtg group but not other ones.
Regarding the formatting. SecurityManagerSetup has become such a mix of tabs
and spaces that it is hard to figure out. Would anyone object to a reformating
patch to change this one to just spaces. You lose some history in annotation on
trunk but could always go back to other branches for the annotation if that is
needed.
