To fix it, modify /usr/bin/uiautomatorviewer with this patch:

--- /usr/bin/uiautomatorviewer.ori  2015-03-31 12:23:52.307244926 +0200
+++ /usr/bin/uiautomatorviewer  2015-03-31 12:28:19.849396991 +0200
@@ -74,5 +74,6 @@
 done

 jarpath="$frameworkdir/$jarfile"
+deps="$frameworkdir:/usr/lib/eclipse/plugins"

-exec "${javaCmd}" $javaOpts -Djava.ext.dirs="$frameworkdir" -Dcom.android.uiautomator.bindir="$progdir" -jar "$jarpath" "$@"
+exec "${javaCmd}" $javaOpts -Djava.ext.dirs="$deps" -Dcom.android.uiautomator.bindir="$progdir" -jar "$jarpath" "$@"

I just reported the bug here: https://bugs.launchpad.net/ubuntu/+source/androidsdk-tools/+bug/1438629

EDIT: Or better:

sudo ln -s ../../lib/eclipse/plugins/org.eclipse.jface_3.8.0.dist.jar /usr/share/java
sudo ln -s ../../lib/eclipse/plugins/org.eclipse.core.commands_3.6.1.dist.jar /usr/share/java
