This community has been providing some great library features for
taming parallelism in Java.

When it comes to tools for parallel performance debugging, it looks to
me that Java is trailing behind C++/Intel's ParallelStudio, or
C#/Microsoft's Visual Studio. When working with Java programs, what
are the tools that you recommend for:
- identifying threading correctness issues (e.g., data-races, deadlocks),
- identifying performance issues (load imbalance, synchronization
contention, false sharing)

best,
Danny
