Abstract
A method and apparatus are provided for detecting data races that overcome the limitations of the prior art. In some embodiments, this is accomplished by detecting a first access to an object, determining whether the first access is associated with a suspicious pattern, automatically refining a pattern detection granularity from the object to a memory location within the object if a determination is made that the first access is associated with the suspicious pattern, and reporting the data race if a second access associated with the suspicious pattern occurs at the memory location after the pattern detection granularity is refined.
