My initial reaction when seeing this PR is to wonder why it can't be generated at build time but from the discussion, it seems like it's a subset symbols, just the functions used by libjvm or is it all the native libraries?

I just did a nm command and did a grep of " T " . That way i got all the symbols for math libraries. There were additional parsing instructions to remove the first column and remove periods at beginning.

Then we had to remove certain symbols that are dependent on DFP symbols and xlc17 doesn't support them yet, So we had to trim down the list further, which is why it now becomes a list to be maintained.
