I haven't done C programming in nearly 2 decades so I don't know if that struct is considered one string or several.

It's a single string; there're no commas separating the lines, i.e., the entire thing will be printed if you simply do

printf("%s", vs_source[0]);

 Trying vs_source[1] will go out of range immediately.

I guess it must only be null terminated once which means that there is only 1 element in the array.

This is correct. String literals are automatically null-terminated in C and C++, and due to the fact that the author does not separate the different lines (e.g. commas), there's only an array with a single null-terminated string.

When you send java strings I guess they are null terminated so there is more than 1 element.

And this was, ultimately, the cause. A really minor oversight during code translation that became difficult to spot after the fact and sent me on a completely different path.

Anyway, it's a good thing that:

  1. The issue has been fixed
  2. The underlying cause was identified

Thanks for the help :)
