Wenn man den Test nur mit long-param ausführt kommt diese exception hier:

[marekadare]

Und nur double-param geht ohne exceptions

[kKdH]

Could you post the pice of code you used to reproduce the issue?

[marekadare]

I commented out the other params in the EventDispatcherFactoryImplTest.java for the test_createEventDispatcher_ForHandlerWithPrimitiveParameter() test like this:

public static class TestHandler_WithPrimitiveParameter
{
//        @Handle(TestEventTypeA.class)
//        public void handle(@Param("boolean-param") boolean param) {}
//
//        @Handle(TestEventTypeA.class)
//        public void handle(@Param("byte-param") byte param) {}
//
//        @Handle(TestEventTypeA.class)
//        public void handle(@Param("short-param") short param) {}
//
//        @Handle(TestEventTypeA.class)
//        public void handle(@Param("int-param") int param) {}

        @Handle(TestEventTypeA.class)
        public void handle(@Param("long-param") long param) {}

//        @Handle(TestEventTypeA.class)
//        public void handle(@Param("float-param") float param) {}

//        @Handle(TestEventTypeA.class)
//        public void handle(@Param("double-param") double param) {}
}
