A DESCRIPTION OF THE PROBLEM :
The JavaFX WebView is very unstable since the latest JRE updates. It's very annoying that the crashes can be reproduced at both java version 8u161 and 8u162.

I thought the idea behind the different versions was that the odd version gets important security fixes and the even version gets a patch-set update....

Our Swing application opens a WebView in a separat JFrame by using the JFXPane. We noticed that the applicatoin crashes if a user switches to another application e.g. Outlook and than back to the WebView by clicking e.g. on a HTML TextField.

The mentioend java frames at the hs_log_pid log files were different at the most crashes:


We tried to write a test program which reproduces the same JVM crash but the crashes were very random.

But in the end we found another way to crash the WebView -> just open http://www.wikipedia.org


REGRESSION. Last worked in version 8u152

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just open http://www.wikipedia.org

REPRODUCIBILITY :
