使用Java 10运行.jar文件时缺少JavaFX应用程序类

Question

My problem is the following: I cannot run .jar files built with java 1.8 after I installed Java 10.

In console, java -version shows:

java version "10.0.2" 2018-07-17 Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13) Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

When I double click the .jar, it does not start, and when I run it from console with java -jar APP.jar, then I get following error: Missing JavaFX application class feedmeclient.FeedMeClient

Interesting thing is that IT WORKS if I revert to Java 1.8 or if I call java 1.8 with full path in console like this: "C:\\Program Files (x86)\\Java\\jre8u162\\bin\\java.exe" -jar APP.jar, then it works with no problem.

APP.jar was built with NetBeans 8.2 Shouldn't Java be backward compatible?

The .jar file contains the MANIFEST and it looks like this:

Manifest-Version: 1.0
Implementation-Title: FeedMeClient
X-COMMENT: Main-Class will be added automatically by build
Implementation-Version: 1.0
Permissions: sandbox
Codebase: *
JavaFX-Version: 8.0
Class-Path: lib/CustomFXComponents.jar lib/FeedMeDataLayer.jar lib/com
 mons-io-2.4.jar
Created-By: JavaFX Packager
Implementation-Vendor: bostinac
Main-Class: feedmeclient.FeedMeClient

So...after a lot of struggle I think I found the problem ... actually there were more problems:

1. It seems that Netbeans 8.2 does not work with Java 9 or 10. I took NetBeans 9 from netbeans.apache.org as Ralf Renz suggested, and I was able to load the project into it, and compile it with JDK 10. Surprise surprise, when I ran it inside NetBeans I get the same Missing JavaFX application class feedmeclient.FeedMeClient error :)

   Also the IDE was struggling to scan the classes and to bring up the pop up where you select your main class of the project to be used. The dialog window will get stuck and no class was found....hmmm strange enough. The project did not had any error, it compiled and build just fine. Then I started to investigate libraries used. I use one library which I build also with Java 8, and this library called DataLayer.jar, was accessing files using JAXB to write and read XML files.

2. Now the main problem: The JAXB used to be inside Java distribution untill now, but in Java 10 they removed it :((( Funny thing is that the IDE would not complain because the DataLayer.jar used as library was already compiled, and I guess it already contained needed classes. But somehow, something was still missing, because when I would ran DataLayer.jar individually, then it would crash because some JAXB symbols could not be resolved. At runtime that confusing " Missing JavaFX application class feedmeclient.FeedMeClient " was thrown even if it had nothing to do with the real reason of the problem.

Good thing is that you can get JAXB as library and use it in project. After I did this, everything went back to normal.
