+- Fix build with jdk9 by specifying java source and target 1.6
+- Added patch:
+  * commons-math3-3.6.1-notests.patch
+    - Disable unit tests, since they are bound to fail. The new
+      methods of java.lang.StrictMath are not implemented in the
+      org.apache.commons.math3.utils.FastMath and the unit tests
+      bail out.
