> parsing doubles will ever be the bottleneck in any of my Java code
In my C# and even in C++, profiler sometimes showed me I am bottlenecked on parsing or printing floats. Happened quite a few times.
In all cases the data was 3D models or similar things. STL, 3MF, VTK, G-mesh, G-code are all text based, either always (looking at you, 3MF consortium) or as an option (STL and some versions of VTK can be either binary or text). Even low-end modern GPUs can easily render 1E+7 triangles these days, thus high-poly 3D models are not uncommon.
Games are not affected because they preprocess the hell out of their assets, optimizing everything they can about the data format. But in CAD/CAM stuff you’re pretty much guaranteed to bottleneck on parsing numbers when loading these text-based formats.
