ABSTRACT:
A thread analysis tool records a set of currently-held synchronization objects and currently-acquired objects when a thread acquires one or more objects, then searches for a lock acquisition hierarchy violation that may cause program deadlock. If a violation is found, it is reported to the user. Software to implement the methods of the analysis tool, and systems using the methods, are also described and claimed.
