Nothing.

Triggers do not mutate, tables do.

P.S. If you are interested in mutating tables, start here and also visit Ask Tom.

Quote:
A mutating trigger occurs in Oracle when the table that originally fired the triggering event is being accessed in the body of the trigger code, directly or implicitly in a procedure, or in a nested trigger called from the trigger body.

This action is forbidden because the table is in middle of a transaction, and referencing the same table again in the middle of the updating action causes the trigger to mutate.
