There are known issues regarding ProgressIndicator and unintended CPU
usage. These will be fixed in JDK 9, but the work is pending new API in
the scenegraph related to knowing exactly whether a Node is actually
'tree visible' or not.

I finally pinpoint the problem with my application. The culprit is
ProgressIndicator with undetermined state. There are couple places in my
application I used a stack pane to hide a ProgressIndicator at back. Then when
I run some task in background thread, I will bring that progress indicator to
the front. It seems that those progress indicators are running in the
background even though they are not visible at all. On a MacBook Pro 13 inch,
even I leave the application idle, it took 20-25% CPU constantly. After removed
all those progress indicator, on the same laptop, idle application only takes
less than 1% of CPU.
Thanks all for your help.

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.

This must be something else then. How many cores are on the that MacBook? I’m
thinking maybe there are four cores and 25% CPU could indicate that there is
one thread stuck in a busy loop. That could explain the heat.
Do you have any animations running? A static application just sitting there
shouldn’t have noticeable CPU usage. I have tons of stuff running now, not
JavaFX though, and CPU usage is around 2%.
What is the minimal application that exhibits the issue?

Thanks for the info. What entry should I put into info.plist?

Yes, 8u77 has the FX fix for this issue:
https://bugs.openjdk.java.net/browse/JDK-8132775
However, due to the way Apple chose to enable this, you will need to
package your application with the appropriate entry in the Info.plist
file.
The equivalent AWT fix --
https://bugs.openjdk.java.net/browse/JDK-8041900
-- is fixed in 8u92 which is scheduled to be released next month.

What version of JavaFX are you running?
There is a known issue, where JavaFX (and AWT/Swing) trigger activation
of
the discreet GPU. I believe for FX the issue has been resolved in the
latest version, but the equivalent AWT fix hasn't made it to a released
version yet.

application, MacBook cooling fan will kick in and running high, just a

the CPU usage is not extremely high and average out about 25% and

on
this issue?
