For the HotSpot VM, a hot spot is a section of bytecode that has been
measured by HotSpot's internal profiling capabilities as one a lot of
time is being spent executing. Based on this observation, HotSpot will
JIT and aggressively optimize this section of code to boost performances.

If you don't know what to do with a section of code you spend a lot of
time in, you call it a bottleneck. Otherwise, if you know how to
optimize it, then it becomes a hot spot :-)
