STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile the test program below as described. This requires the guice-5.0.1.jar and the javax.inject-1.jar 

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
code compiles and works
ACTUAL -
An exception has occurred in the compiler (16.0.2). 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, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.

CUSTOMER SUBMITTED WORKAROUND :
replace

            bind(new TypeLiteral<Foo<?>>() {}).toProvider(new SomeProvider<>(Key.get(new TypeLiteral<>() {})));

with

            Key<Foo<?>> xxx = Key.get(new TypeLiteral<>() {});
            bind(new TypeLiteral<Foo<?>>() {}).toProvider(new SomeProvider<>(xxx));

makes the code compile (not crash).
