I'm not too surprised.  Just ignore this.

Thanks.  If you could write a little program to check that one or more
of these constants is correct, that would be helpful.  Easiest is
probably to just cut-and-paste the relevant output into a pure C++
program (writing CNI code to do this is more effort).

If it's possible without a lot of work, this is preferable.  If it
isn't possible, well, I don't remember ever looking at a float or
double constant in jcf-dump's output.
