[9] RFR (L): 8057042: LambdaFormEditor: derive new LFs from a base LF

[Peter Levart]

Hi Vladimir,

I'm sure you and John have thought about it through, but I'll ask 
anyway. Are cached LambdaForms going to stay around forever? What about 
using a WeakReference<LambdaForm> (LambdaFormEditor.Transform could 
extend WeakReference). This way unused LambdaForms would get GCed.

Regards, Peter
