I started using Java for similar reasons. I used to write performance
models simulating very complicated multiprocessor servers. A cache miss
could produce several messages causing actions in different components
of the processor-memory interconnect. The cache miss was completed when
several conditions had been all been met, and the order depended on the
states of various queues.

I wrote one in C++. It worked, and did not leak memory even when run for
several days. The problem was that I had spent significant effort to
achieve that result.

The next time I used Java, and got the same effect for zero programming
effort.
