I havn't tried but I think not as the generated bytecode (.class
files) will have a plain List in there and the compiler has inserted
casts in the appropriate places. You can see for yourself what the
compiler generates when you print some info via the java.lang.reflect
package for your class, you'll see that there isn't any generic stuff
in there.
