Missing custom Java class: DummyJavaClass

[apjanke]

Looks like we're missing both the source code and JAR file for the Java bits of this benchmark.

>> bench_matlab_nops

Matlab R2019b on MACI64  
Matlab 9.7.0.1737446 (R2019b) Update 9 / Java 1.8.0_202 on MACI64 Mac OS X 10.16 (eilonwy) 
Machine: Apple M1 Max, 10 cores, 64 GB RAM 
nIters = 100000 

Java tests errored: No class net.apjanke.matlab_bench.bench_nops.DummyJavaClass can be located on the Java class path. Skipping.

Operation                        Time (μsec) 

I wonder if that's sitting over in janklab-core somewhere. Or if it's machine-local on my old eilonwy laptop.

Oh, wait; there's the source code; just no .class or .jar file.

Oh, and look at this in .gitignore:

# Compiled class file
*.class

Here's where bench_matlab_nops.m pulls it in:

myJavaClassDir = fileparts(mfilename('fullpath'));
[...]

% Prep

% HACK: Get our Java classes on the path
% Be sloppy and skip the try/catch or onCleanup() just in case that affects
% our timings
javaaddpath(myJavaClassDir);

So the .class file probably never got committed.

That dir layout is kinda gross, too. Change that.

Got a start on this in c158dd7 but it's not working yet. Maybe something having to do with the target Java version I'm compiling to.
