(CR 6822370 actually represents a cluster of bugs that are now thought to be related by a common underlying issue). Briefly, we have a lost wakeup bug in the native C++ Parker::park() platform-specific infrastructure code that implements java.util.concurrent.LockSupport.park(). The lost wakeup arises from a race that itself arises because of architectural reordering that in turn occurs because of missing memory barrier instructions. The lost wakeup may manifest as various 'hangs' or instances of progress failure.

This article, the first in a two-part series, guides you around the many pitfalls associated with benchmarking Java code. Part 2 covers the statistics of benchmarking and offers a framework for performing Java benchmarking. Because almost all new languages are virtual machine-based, the general principles the article describes have broad significance for the programming community at large.
