+Based on the upstream fix for the java8 compilation issue.
+Simplified patch.
+Upstream version of patch does not work with this source tree.
+
+The issue is that in java8 it is an error to pass null to
+removeAll. Results in null pointer exception. java7
+behaviour was to return the list unmodified.
