Jörgen Rydenius commented on VELOCITY-731:
------------------------------------------
Great news! A trivial detail though, shouldn't fix version be 1.6.3 on 1.6
branch since 1.6.2 is already out?
> Velocity 1.6 performance is degraded by introduced toString() calls

> As part of VELOCITY-531, r686428 introduced frequent calls to toString() just
> to check if toString() != null. If toString() implementations are slightly
> complex, and very frequently executed, these calls will degrade the site
> performance. Are they at all necessary? What kind of object would use null as
> a return value for toString()? Is it possible to remove these toString()
> calls from the velocity code again?
