@dholmes-ora I have created a CSR, so please confirm it.

As you say, if the error report is output only to stdout or stderr, information can be lost. Similarly, if the error report print to the hs-err log file only, there may not be any files left.
I would like to create an option to leave both in order to increase the possibility of a post-mortem investigation.
