The Events classes collect events in a circular buffer that gets dumped into the hs_err files. There are different sections to sort out different types of events. See:

  // A log for internal exception related messages, like internal
  // throws and implicit exceptions.
  static ExceptionsEventLog* _exceptions;

  // Deoptization related messages
  static StringEventLog* _deopt_messages;

  // Redefinition related messages
  static StringEventLog* _redefinitions;

  // Class unloading events
  static UnloadingEventLog* _class_unloading;

There's also a buffer for non-categorized events:

  // A log for generic messages that aren't well categorized.
  static StringEventLog* _messages;

I propose that we create a separate buffer for VMOperations.
