Yes, this would be extremely helpful, but it's difficult to implement
performance hooks and analysis hooks, especially in a cross-platform
machine-independent environment. We don't yet have such hooks as part
of the base JDK.

Such tools are often very system-specific since they depend on the
particular threads implementation. If you are by chance working on
Solaris, you should check out the Solaris MT tools (see also

p.s. I think there is a great market for good Java tools and I hope people
will go after that market! There are some great tools for
multithreaded programming on Solaris (for example, lock_lint which
finds deadlocks and data races) that would be great to have in Java.
