I've created this:
  6980747: (process) Runtime.exec can fail due to SecurityException (lnx)

The fix looks fine.  It might be good to indent the second and third 
lines of the test summary to make it easier to distinguish the test tags 
from the text. On Windows I assume the "env" command will run the Cygwin 
or MKS "env" program rather than the built-in "env" command. It probably 
matter as the test doesn't actually need the child process to do anything.
