Those seem to me to be very good reasons to run with a 1.6 JVM if at all 
possible. I think that should be our strong recommendation, for the 
reasons you state.

Are there any negatives, other than not being able to use "Since 1.6" 
API features in the River source code, to keeping the code 1.5 
compatible, and compiling with 1.5? A 1.5 classfile can be used with a 
1.5 or 1.6 JVM.
