I compiled using the verbose command and I got

$ javac -verbose RunnableExample.java

I have also tried changing to Thread constructor to take in just a
String and I get the same cannot find symbol error. If I create a thread
with a blank constructor it will compile; however, if I call start() on
the thread, the run() method is not invoked.
