A requirement of River to use a minimum JRE of 1.5 could be applied to AR1
because Java is upwards compatible.
AR1 could be compatible with 1.4 (based off jini2_1). However, by requiring
1.5, committers could generify some classes in the core architecture for
type safety additions to River in later releases.

I am asking for the community to choose a minimum version of Java greater
than 1.4.x to sail up the River .

I personally would like to see 1.6 as the minimum (GPL'ed Java) .
