RFR: 8213703: LambdaConversionException: Invalid receiver type not a subtype of implementation type interface

[Vicente Romero]

Please review fix for [1] at [2]. Similar issues has been reported and 
fixed in the past, see for example [3]. The approach to fix these type 
of bugs has been that if the target interface has parameters which are 
intersection or union types then we bail out and produce a lambda 
instead of a method reference. As in this case we are dealing with a 
capture variable it was defeating the our checks.

Thanks,
Vicente
