+openjdk-lts (11~28-3ubuntu2) cosmic; urgency=medium
+
+  * debian/rules:
+    - limit the tests that we run for the hotspot, langtools,
+      and jdk testsuites to improve build times and also to
+      prevent running unstable or failing tests.
+    - fix 'if' clause for definition of the TIME command.
+    - remove guava jar from test classpath, no longer required.
+  * debian/control, debian/control.in: add a breaks clause to
+    clojure1.8 <= 1.8.0-7ubuntu1~.
