JavaFX Application Heat up MacBook Pro

[Chien Yang]

BTW, I did a 15 min run of Ensemble8 testing a series of programs on my 
MBP 15 this morning. The machine remains cool and its fan remains off. 
Can you provide the steps on how you heated up your MBP running 
Ensemble8? Did you have other programs running?

Thanks,
- Chien
