      Description

      For Evergreen, we want to detect if already too many logs were generated before the Evergreen Jenkins Plugin even had time to start up.

      The rationale being: if there are already 256 logs when plugin startup state is attained, then there is something (very) wrong per-se.

      The goal is to be able to do something like:

      if (Jenkins.logRecords.size() >= WebAppMain.getDefaultRingBufferSize()) {
          LOGGER.log(Level.SEVERE,
                     "The Jenkins logs buffer is already full. " +
                             "Some logs might have been missed, and so many logs shows something probably very wrong! (max={0})",
                     maxNumberOfLogs);
      }
      

      Currently, as an intermediate shim, I'm using reflection. In addition to being dirty, this is likely to become even more an issue to support Java 9 when using such hacks is being made harder and harder.
