I don’t get what is talking about. Maybe is a bad translation because
in the similar English page talk about “prompts.”
I would say your “bad translation” assessment is correct. It seems the translation might be a bit “off” or was done by a non-native speaker. Heck, checking with some online Spanish-to-English dictionaries it seems “petición” can also be translated as “request.” Knowing that perhaps “restore requests”—instead of “petitions”—makes more sense as a translation?
Because ultimately both the Spanish and English versions of the page have the URL endpoint of
restore_prompts.xml in them; so we can assume that they are both attempting to convey the concept of “restoring prompts.” So knowing that is the case, this English translation sums it up:
Starting with 7u51, users are given an option to restore the security
prompts for any prompts that were hidden more than 30 days prior to
installing the latest Java release.
Basically Java just has security prompts and there is now an option—as of version 7u51—for the user decisions made when those prompts came up to be “restored” or I would better state as “forgotten” or “reset.”
If you feel this is confusing it might be worth it to contact Sun Java tech support and point out their Spanish help pages are mis-translate. Screenshots below for reference.
