Add JFR event indicating explicit System.gc() call

    XMLWordPrintable

Details

    • gc
    • b26

    Description

      Create an event explicitly for System.gc, always enabled and with stacktrace enabled.

      The reason is that when one or more of the gazillions of frameworks you depend on have decided to attempt to force a full gc every once in a while (without having knowledge about everything else that is in use), this would be an easy way to find the location.

      The stacktrace should be the one from the caller of the system.gc call.
