ejbSelect methods with same name, diferent signatures does not work

Multiple ejbSelect methods with signatures like the following does not work.

OtherLocal ejbSelectOther(SomethingLocal ejb, Long id)
OtherLocal ejbSelectOther(SomethingLocal ejb, String name)

This is what happens:

Renaming the methods to something like the following works fine.

OtherLocal ejbSelectOtherById(SomethingLocal ejb, Long id)
OtherLocal ejbSelectOtherByName(SomethingLocal ejb, String name)
