Re:Java garbage collection can be really slow by Retric on Saturday April 23, 2016 @08:49AM (#11555334)
Boring C++ is often faster than boring Java code. It's safer to write hacky Java, but code reviews should not let hacky code in.

C++ costs more, but that's often a non issue for a trading floor. Security is much simpler in the Java world, but also possible in boring C++ code.

Making small changes is really more a question of your code than anything else IMO. There is a lot of crazy C++ and Java code out there.

Now for basic CRUD apps Java is a clear win. For high preformance trading that's an open issue. But, IMO there are much better languages to use.
