java.lang.ClassNotFoundException: javafx.application.Application

I try to compress my javafx app into jar, and when i run:

java -jar /home/roroco/Dropbox/rbs/ro_cmds_global/j/fileToClip/build/libs/server-1.0.jar -cp /home/roroco/Downloads/jdk1.8.0_74/jre/lib/ext/jfxrt.jar

it raise this error:

Caused by: java.lang.ClassNotFoundException: javafx.application.Application
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

I'm sure jfxrt.jar include javafx.application.Application

roroco@roroco /tmp/fileToClip $ jar tf 
/home/roroco/Downloads/jdk1.8.0_74/jre/lib/ext/jfxrt.jar|gr Application\.class
com/sun/glass/ui/Application.class
com/sun/glass/ui/gtk/GtkApplication.class
javafx/application/Application.class

why it will raise "ClassNotFoundException"?

update

my java version is:

roroco@roroco ~/Dropbox/try/j/try $ java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~14.04-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

I find the reason: since my java version is:

roroco@roroco ~/Dropbox/try/j/try $ java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~14.04-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

i should use oracle bin/java instead, in my case, I use following will work:

/home/roroco/Downloads/jdk1.8.0_74/bin/java -jar /home/roroco/Dropbox/rbs/ro_cmds_global/j/fileToClip/build/libs/server-1.0.jar
