I thought the "Type Erasure" implementation of generics erases everything related to generics at compile time.
What information is available at runtime?
See [1] for a brief example. It's in the attributes of a field/method and can be found in the constant pool. I'm not very familiar with the details but the (a lot) information can be reconstructed from bytecode otherwise Guice couldn't inject my generic fields. For details, the JVM spec is the reference to look at I guess :-)
Best, Marcel
Best regards,
Kai

Not with generics. Would be awesome to have.
That is a Java thing, generics are not available at runtime.
The information about generics is still in the bytecode. DI frameworks like
guice and spring can handle generics (with some limitations) and eclipse
could do so too. the question about generics pops up quite often during
training or hands-ons.
