FULL PRODUCT VERSION :
Java(TM) SE Runtime Environment (build 1.8.0_72-ea-b05)

ADDITIONAL OS VERSION INFORMATION :
Tested on both Darwin Kernel Version 13.4.0 and on Windows 8.1 with same problem

A DESCRIPTION OF THE PROBLEM :
I have an HTML page that includes an SVG with several <path> elements that I load into a WebEngine instance. After an upgrade from Java 1.8.0_45 to 1.8.0_72-ea-b05 many paths disappear from the resulting visualization. The bug is 100% reproducible using the following testdata: https://gist.github.com/mbostock/1044242

The problem only occours when there are a large number of paths. For example, with 20-30 path elements in the SVG things look good (even when the paths overlap in the visualization). As soon as I increase the number of paths to around 300, many paths aren't visible on the page.

This worked fine with Java 1.8.0_45 so the bug has been introduced since.

REGRESSION. Last worked in version 8u45

ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Download the the HTML and JSON file from the following gist: https://gist.github.com/mbostock/1044242
2. Load the downloaded HTML into a JavaFX WebView:
        WebView browser = new WebView();
        WebEngine webEngine = browser.getEngine();
        webEngine.load(theContentDownloadedInStep1);
3. Show the WebView component (I place it in a JavaFx Tab).
