Fatal error when running on Ubuntu 16.04.2 (64-bit) and Java 9 #15

Installed OpenStego using the deb from the 0.7.1 release in a desktop running an Ubuntu 16.04.2 LTS (64-bit). It did not run when using the GUI (.desktop file), so I tried using the CLI, and it gave the following error:

$ java -jar /usr/share/openstego/lib/openstego.jar 
net.sourceforge.openstego.OpenStegoException: java.lang.NullPointerException
    at net.sourceforge.openstego.util.PluginManager.loadPlugins(PluginManager.java:65)

As a reference:

$ java  -version
java version "9"
Java(TM) SE Runtime Environment (build 9+175)
Java HotSpot(TM) 64-Bit Server VM (build 9+175, mixed mode)
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:    16.04
Codename:   xenial

FYI - It does work when using Java 8 on the same machine.

Java 9 is still not officially released, and will be released in September only. Current builds might have bugs. Please wait for official release and test with the same. If issue still persists, I'll take a look into it.

Hi, I'm facing this issue now on Windows 10 64bit with Java 9 official release. This should be re opened.

Fixed with release 0.7.2
