I was playing with parallel programming, and experienced "undefined behavior" when storing into an Associative Array in parallel. Guarding the assignments with a synchronized barrier fixed it, of course. And obviously loading down your raw AA with thread barriers would be foolish.

But this set me searching through the library for a standard Associative Array construct which is thread safe? It didn't jump out at me. I know I can place such a thing within a synchronized class, but I was wondering if there's a standard AA which has the standard usage but is safe when called in parallel?

Thanks,
Andy
