java-systemd not compatible with dbus-java v5

[mbaudier]

With the latest major release of dbus-java (v5.0.0), Systemd.get().getManager() fails with:

java.lang.NoSuchMethodError: org/freedesktop/dbus/connections/impl/DBusConnection.getConnection(Lorg/freedesktop/dbus/connections/impl/DBusConnection$DBusBusType;)Lorg/freedesktop/dbus/connections/impl/DBusConnection; (loaded from xxxxxxx/org.freeedesktop.dbus.5.0.jar by org.eclipse.osgi.internal.loader.EquinoxClassLoader@99aa01a5[org.freeedesktop.dbus:5.0.0(id=183)]) called from class de.thjom.java.systemd.Systemd (loaded from xxxxxxxxx/de.thjom.java.systemd.2.1.jar by org.eclipse.osgi.internal.loader.EquinoxClassLoader@3fb8805f[de.thjom.java.systemd:2.1.0(id=204)]).

Apparently the DBusConnection.getConnection(DBusConnection.DBusBusType.SYSTEM) method has been removed.

I had the same issue with some low-level code which uses dbus-java directly, and it worked by using:
DBusConnection dBusConnection = DBusConnectionBuilder.forSystemBus().build() instead.

Thanks for sharing this, I might have a look into it, if I find the time. :/
