jmap prints messages to stderr

XMLWordPrintable

      jmap prints logging into stderr instead of stdout:

      Attaching to process ID 9552, please wait...
      Debugger attached successfully.
      Server compiler detected.
      JVM version is 12.0-b01
      finding class loader instances ...

      However note it does not print them, for example, for jmap -histo on live process (?).

      In addition, there is jmap-specific debugging output which does not seem to be relevant to anything:

      (multiple lines)
