PulseLogger negative start time

[Anton Epple]

Hi,

 

I need some help interpreting PulseLogger output. Sometimes I see log messages like this:

 

[947 16ms:0ms]

Pulse 948 shows an initial Layout Pass starting at -2051ms. Does this Layout pass with its negative starting point really belong to pulse 948, or is this a bug?

 

The project has a single scene. I’m running this on a mac (OS X 10.12.6) with  java 1.8.0_112-b16 (Java HotSpot(TM) 64-Bit Server VM (build 25.112-b16, mixed mode)) with Options: -Djavafx.pulseLogger=true -Djavafx.pulseLogger.threshold=100

 

Thanks
