Ah, nice. I can indeed use the code in `print_jni_stack` to print the native stack. I propose making this configurable:

  product(ccstr, TraceClassLoadingCause, nullptr, DIAGNOSTIC,               \
          "Print a stack trace when loading a class whose fully"            \
          "qualified name contains this string ("*" matches "             \
          "any class). Append ":0" to print the Java stack (default), "   \
          "":1" to print the native stack and  ":2" to print "          \
          "both stacks.")                                                   \
