      Description

      JDK-8194312 introduced calls to "log_info(oopstorage, ref)()". However, that has added an overwhelming number of logging message when -Xlog:oopstorage* is set on commandline.

      For example, running Dacapo's tradesoap and observe the lines of messages:
      $ java -Xlog:oopstorage*=<level> -Xms500m -Xmx500m -jar dacapo-9.12-bach.jar tradesoap
      info | debug | trace
      107934 | 112990 | 112701

      It might be reasonable to change the log levels for (oopstorage, ref), although JDK-8210712 refers to changing the -XX:+PrintReferenceGC replacement and we can filter the messages of the oopStorage logging with -Xlog:oopstorage+blocks.
      This bug is therefore to determine if it is reasonable or not to change the verbosity in the code.
