* java_certs : Not enough info on error
Just bumped into an issue when the message was "Internal module failure, cannot extract public certificate from pkcs12, error: "
Seems that the issue #2560 doesn't cover all cases. To make debugging easier, I propose to add error output on json return instead of only expose standard output.
* java_certs - add missing fragment message
* Word-smithing.
