How to understand and solve EXCEPTION_ACCESS_VIOLATION in jni using javafxpackager and x86_64 windows exe?

I am develop setup packager for java application used rhvoice speech synthesizer, which not need administrator's privilege on windows (so i can't use sapi version).

To solve it i am used andoid jni code with formal minimal fixes and all works well on both architectures x86 and x86_64, when java application executed using java.exe from jar files.

But, when i make windows exe application using javafxpackager or for example packr (they are used jvm.dll to work), x86 version work well but x86_64 stops with java EXCEPTION_ACCESS_VIOLATION:

Some years ago in 2014-2015 this method worked without error on windows 7 and 8 on both architectures, but old build does not work well on windows 10 and was recompiled using Visual Studio 2017.

How i can detect a reason such error exception. How i can setup debug environment to research this.

When i am changing version of java (oracle or unofical windows builds openjdk), compiler (vs2015/2017) or build environment operating system (win7 or win10) the problem has come sometimes on x86 version packager and exception address changed between inside rhvoice library or java.
