Besides, Specjbb_2005 doesn't do any IO or networking, and these should not be factors in the result.
So although it's a simplistic benchmark where OS tuning may not provide as much benefit as JVM tuning, it still doesn't explain why Solaris is ~15% higher than Linux on the same hardware and JVM (I'm guessing that the tester did not spend as much time tuning Linux as they did Solaris, hence the question).
