createTypeVariable

public static TypeVariable createTypeVariable(TypeVariable typeVariable,

Java TypeVariable is different in various JDK versions. Thus it is not possible to e.g. write a custom TypeVariable which works in either Java7 and Java8 as they introduced new methods in Java8 which have return types which only exist in Java8 :( As workaround we dynamically crate a proxy to wrap this and do the delegation manually. This is of course slower, but as we do not use it often it might not have much impact.

Parameters:

typeVariable -

bounds -

Returns:

the typeVariable with the defined bounds.
