NullPointerException crash when attempting to run

Considering there's no README, I did my best:

stewart@birb serverwiz]$ ant -f build.xml clean compile jar
Buildfile: /home/stewart/serverwiz/build.xml

clean:

BUILD SUCCESSFUL
Total time: 5 seconds

and then, considering there's no instructions on how to run, i tried this:

stewart@birb serverwiz]$ cd build/
[stewart@birb build]$ ls

[stewart@birb build]$ 

I certainly did not expect it to download code and execute it... very unexpected (is it even running what I built?)

This is running on Fedora 24 with openjdk 1.8:

$ java -version
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)

If you look at the messages, it only appears to be unpacking XML files. This is a feature of the tool to always grab the latest XML.

The log messages may be misleading then, because .jar pretty much always means "java executable code" (at least to me):

I added README with build instructions and behavior description of jars.

For the NullPointerException, do you see the GUI come up?

[nkskjames]

Looks like there have been some issues with GTK3 and SWT. For a temporary workaround:

export SWT_GTK3=0

I tested on Fedora24 and this worked for me. I will continue to investigate root cause.

With that work around, the GUI launched for me.

[nkskjames]

I pulled in newest jface jar and it fixes NPE, but the GUI is not pretty without SWT_GTK3=0. The GTK3 themes mess up the colors. You can switch to a high contrast theme and can see everything, but still not pretty. If you use GNOME, you can use gnome-tweak-tool to change theme.

I love how Java is write once and run anywhere.

FWIW, on Fedora 24 it looks fine with SWT_GTK=0 or as default.
