Abstract
Methods and apparatus for converting a lightweight monitor to a heavyweight monitor are disclosed. According to one aspect of the present invention, a computer-implemented method for converting a lightweight monitor to a heavyweight monitor when an object that is owned by a second thread is unavailable to a first thread includes creating a new heavyweight monitor and setting the ownership of the new heavyweight monitor to the second thread. The first thread then enters the newly created heavyweight monitor without being forced to spin lock until the object is released by the second object.
