Support for ResolvableType.getType().getTypeName() on Java 8 [SPR-16535]

[spring-projects-issues]

Dave Syer opened SPR-16535 and commented

Example test that fails:

assertThat(ResolvableType.forClassWithGenerics(Consumer.class, String.class)
		.getType().getTypeName()).isEqualTo(Consumer.class.getName());

I think it just passes the type name property to toString() and that isn't very helpful in this case.

It would be nice for the type name to be the same as the raw type (the same as if I have defined a class that implements Consumer<String> and printed the type name of its interfaces.

I wasn't even aware of that getTypeName() method... seems to be new in Java 8, making Type more than just a marker interface.

I'll make sure to properly expose the type name there and also on toString(), consistent with the JDK's standard Type implementations.

I've implemented the above for 5.0.5, aligning both getTypeName() and toString() with the common JDK types. For 4.3.15, I'll just backport the getTypeName() part (to be bound to Type.getTypeName() when running on Java 8), leaving toString() untouched (since we can't trigger nested getTypeName() calls there on JDKs <8).
