My MacBook Pro is a i5 dual core with 16GB of memory. The minimal application that exhibits the issue is just a simple window with web view and I used D3JS draw a simple graph (only 5-6 nodes). Then just let application sit idle there without doing anything. The CPU will heat up quickly. I put the application in VisualVM, other than JavaFX application thread, the next thread is taking up CPU time is QuantumRender. But my application is just sitting idle, no animation or any user activities.
