> As for reporting generic errors from failed external commands, jpackage will always print the command's output, regardless of whether it is running in verbose or quiet mode. Previously, it would print command output only in quiet mode, assuming that in verbose mode, the output would be printed immediately after command execution. However, jpackage runs some commands quietly in verbose mode; if one of them failed, the user didn't see its output. To address this problem, jpackage will print the output of the failed command in both quiet and verbose modes.
