Obviously something is trying to load the GTK AWT peers which you haven't built:

Caused by: java.lang.UnsatisfiedLinkError: Native library `gtkpeer' not
found (as file `libgtkpeer.so') in gnath
  at java.lang.Runtime.loadLibrary(Runtime.java:763)
  at java.lang.System.loadLibrary(System.java:670)
  at gnu.java.awt.peer.gtk.GtkToolkit.<clinit>(GtkToolkit.java:177)
  at java.lang.VMClass.forName(Native Method)
  at java.lang.Class.forName(Class.java:233)
  at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:583)
