Abstract
A mechanism is provided for switching a locking mode of an object in a multi-thread program. The mechanism acquires, during execution of the program, access information related to accesses to the object by a plurality of threads. The object supports a single-level locking mode and a multi-level locking mode. The single-level locking mode is a mode capable of locking the object. The multi-level locking mode is a mode capable of locking the object and fields in the object respectively. The mechanism switches the locking mode of the object between the single-level locking mode and the multi-level locking mode based on the access information.
