Hello Fernando, I'm not familiar with this test or the area, but if this change is just to make available jtreg logs (in a separate file) to allow for debugging a currently intermittent test failure, then there are ways to change the jtreg output log limit in our CI, without having to change the test code - I can show you the command, offline, to do that.

As far as I remember, we don't have a precedence of changing tests to write out to additional locations to bypass the jtreg log limit.
