Documentation to TEventList::GetIndex(Int_t entry) says that
...
If no match found, function gives nearest element smaller than entry.
---------------
This need to replace to :
...
If no match found, function return -1
--------------
(see code of TEventList::GetIndex. This behavior are required by
TEventList::Contains(...))
