nothing intrinsically wrong with using multiple engines, as long as
they're both set up properly. the code below does give a hint
though...

it all looks good up to here. but here, we see that if any Exception
is thrown above, then the actual call to velocityEngine.init() never
finishes, the exception is logged, and then the application is allowed
to continue! this is poorly written, because an uninitialized
VelocityEngine (at least in Velocity 1.4) is a *major* problem. they
need to either let the exceptions go, throw a new wrapping exception,
or else try again to init the engine.
it certainly looks like some exception is thrown either prior to or
during the call to init(props). can you find this Exception in your
logs?
