Good point. I triggered this error and it didn't look pretty:

> java.exe -XX:NativeMemoryTracking=blah
Syntax error, expecting -XX:NativeMemoryTracking=[off|summary|detail]Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I noticed a few other spots in this file where trailing `\n` is missing. I'll fix them here as well.
