That depends on the geographic distribution, though. Also, we are talking of a 25% larger pool.

You could say the same about C++ developers. Most of the C/C++ jobs are in embedded devices, which differ vastly from HFT environments.
Because the pool of Java devs is only marginally wider than the pool of C++ devs? 5.4M C++ devs vs 7.1M Java devs is not a massive difference in pools:

And while I don't have numbers for it, my experience has been that the vast majority of Java devs have very little experience with the kind of specialized use of the JVM that low latency programming requires. On the contrary, I've found it difficult to hire for high-performance Java codebases, because the way they are written is completely different from how "normal" Java is written, so you need to retrain devs used to writing "normal" Java.
