A DESCRIPTION OF THE PROBLEM :
If a raw type is used with a lambda, javac throws an assertion.
The same code compiles with the Eclipse compiler.
It is similar to JDK-8074381, but that was resolved in b56

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile supplied source code using javac

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Succesful compilation or a warning.
ACTUAL -
Assertion from javac

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Information:Using javac 1.8.0_102 to compile java sources
Information:java: An exception has occurred in the compiler (1.8.0_102). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.function.Function;

CUSTOMER SUBMITTED WORKAROUND :
Do not use a Raw type, specify e.g. <Object>
