There is known issue with WebView forcing the JavaVM to crash with an EXCEPTION_ACCESS_VIOLATION filed at https://javafx-jira.kenai.com/browse/RT-35262 (unfortunately, free Jira account needed).
The WebView seems to have issues with garbage collecting issued JavaScript statements, so after some amount of JavaScript it will turn down the JVM. We have observed this only on 32-bit JVM.
A fix has been deferred from Java 8u40 to Java 9, which is not even sheduled yet (vaguely probably in 2016).
