I'd like to set up a large linear programming model to solve an interesting problem. I would be most comfortable in Java. What tools/libraries are available?

There were several suggestions from an earlier question that I posted:

and possibly more...

I used lp_solve with success. It looks like there is a native Java API, but I've only used the text file interface. It supports the semi-standard MPS and LP file formats, which I found more convenient for trying out different solvers (such as glpsol).

    I wouldn't recommend lp_solve for several reasons. 1) Crashes regularly for large LP problems. 2) Very hard to debug errors/crashes (e.g., xfree memory free error, corrupted double linked list etc. 3) Very bad API (the file interface is decent) but the array based C style API is horrible. – Apoorv May 18 '13 at 11:49

Currently, google digs up this Java Linear Programming libs:

    @Kyll Thanks for the comment. Was not aware of this guidance yet. FWIW, this question paraphrased what I was looking for, which was how I found it in the first place. Next, I summarized my findings. – Jörg Mar 07 '16 at 14:22
