src/share/vm/runtime/java.cpp:

+       tty->print("Native memory tracking is off due to ");
+       tty->print_cr(MemTracker::reason());

You can use one line to print that output:

+       tty->print_cr("Native memory tracking is off due to %s", MemTracker::reason());

But looking at MemTracker::reason the final output might look weird:

"Native memory tracking is off due to Native memory tracking is not enabled"
