[Windows] JavaFX crash in WebPage.twkOpen in 8u112 when closing WebView while debugging

To verify the issue https://bugs.openjdk.java.net/browse/JDK-8163252,
we download Java 8u112 (b04) from https://jdk8.java.net/download.html,
and execute it.

However, I found that this JavaSE8u112-ea b02 Windows-x86 JVM crashed when executing WebPage.twkOpen of JavaFx.
Refer to attached hs_err_pid12584.log for detail of the crash.

This crash will occur neither in SE8u92 nor SE8u102.

This crash can be reproduce with following steps.

Attached DebuggerCrash.java is a test case to reproduce:
1) it requires jetty and javax.servlet-api in the classpath (attached)
2) it require you to run the test case, then attach the Chrome Browser debugger to the vm by putting this url in Chromel:
chrome-devtools://devtools/bundled/inspector.html?ws=localhost:9222/devtools/page/1
3) Right click the page and press reload, the vm will crash every time for me and another PCs we've tested on . The same steps in Java 8 U92 have never crashed.
