The following schedule produces the "You can only use one percent sign to separate the cron from the parameters." error message.

H 8 * * * % SPRING_PROFILE="qa"; TEST_SUITE="Regression.xml"
H 8 * * * % SPRING_PROFILE="prodlive"; TEST_SUITE="ProdSmoke.xml"

These lines look well formatted to me.  I believe something is wrong with the way the lines are being parsed.
