A DESCRIPTION OF THE PROBLEM :
Calling a method via the ::-Operator on a parameter of a generic Type that implements an Interface and extends an abstract class throws a LambdaConversionException if the method is from the interface.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the minimal example provided as source code using java 8

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No crash
ACTUAL -

CUSTOMER SUBMITTED WORKAROUND :
Works in newer Java Versions than 8
