  The .jar file "org.eclipse.swt.gtk_3.1.0.jar" is SWT, but packaged as
an Eclipse plugin.  libswt-pi-gtk-3128.so is one of the JNI shared
libraries required by SWT.  It is located inside the SWT plugin .jar,
and is extracted on-demand by Eclipse.

  Upstream at eclipse.org, we provide a separate SWT download, which is
just swt.jar alone along with all of the shared libraries.

  IMHO, this package should be providing something similar.  An swt.jar
file, and the .so files, suitable for building standalone applications.

    libswt3-gtk2-3.1.0_fc-0.M6.22

  I don't think it's doing that currently.
