Javac compilation fails for type-casted lambda expression instrumented by Clover

A following code:

Object o = (Runnable) () -> System.out.println("lambda expression with class cast");
((Runnable)o).run();

is being instrumented by Clover as follows:

Object o = (Runnable) RECORDER.lambdaInc(111, () -> System.out.println("lambda expression with class cast"));
((Runnable)o).run();

As a result javac is unable to compile such code - it cannot infer proper type from the context:

error: incompatible types: cannot infer type-variable(s) I,T
(argument mismatch; Object is not a functional interface)
where I,T are type-variables:
I extends Object declared in method <I,T>lambdaInc(int,T)
T extends I declared in method <I,T>lambdaInc(int,T)

Workaround:

Change lambda from expression to block:

Object o = (Runnable) () -> { System.out.println("lambda expression with class cast"); };

or

Remove class cast:

Runnable o =  () -> System.out.println("lambda expression with class cast");

Possible fix:

Wrap class cast inside lambdaInc():

Object o = RECORDER.lambdaInc(111, (Runnable)  () -> System.out.println("lambda expression with class cast"));
