valid SAM type not accepted

[Mark Mahieu]

Maurizio,

Dunno if this is of any use to you, but I think I've just tickled the same (or a similar) bug with a slightly different example, which reduces to:

	class DoubleVision {
		
		interface A extends Runnable {}
		interface B extends A, Runnable {}

		B b = #{};
	}

	$ javac DoubleVision.java

	DoubleVision.java:6: invalid target type B for lambda conversion
	        B b = #{};
	              ^
	  reason: the target type of a lambda conversion has multiple non-overriding abstract methods
	1 error
