        Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)


        ADDITIONAL OS VERSION INFORMATION :

        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
