[11u] RFR (XS): 8261020: Wrong format parameter in create_emergency_chunk_path

[Denghui Dong]

Hi team,

This email was not sent successfully due to a problem with the mailing list last week, so I resend this email. Thanks to Christoph for his help:)

Could I have a review of this small fix?

In create_emergency_chunk_path, the call to jio_snprintf used a wrong format parameter "repository_path_len".

This bug was introduced in 8217362(Emergency dump does not work when disk=false is set) and fixed in 8226511(Implement JFR Event Streaming),
It is currently unacceptable to fully backport 8226511 to 11u, so I filed a new issue to fix this problem.

Thanks,
