Run 25k times in sequence:

for /l %%x in (1,1,25000) do (java -cp ... MyClass)

Run 25000 times in parallel:

for /l %%x in (1,1,25000) do (start "" java -cp ... MyClass)

If you want to limit the parallelism (which you should for such high numbers) then you need a bit more logic. One example is given in this answer.

Why not just put the loop inside your client program? or write another class that calls it 25,000 times? But:

I just want to test my server how many connections it will accept without any delays

This test won't test that, as all the connections are sequential: each previous connection is closed by the program exiting before the next one starts. If your server doesn't pass that test there is something very seriously wrong with it. A more interesting test would be how many concurrent connections it can handle.
