Found the cause: calling ctx.getMessages() or ctx.getValidationErrors() 
triggers the creation of the Flash Scope even if no messages or errors 
are subsequently added to them.  I was fetching these at the top of the 
action and assigning them to a variable, then using them in the message 
& error handling code later on in the method.

I think there's a possible RFE here:

Flash Scope should not be saved unless it is non-empty.

Thoughts?
