+ * TEST NOTE
+ * With JDK9, this this test has been transformed into a NEGATIVE test.
+ *
+ * Generally speaking, this test should check a feature not in at least
+ * one of the currently supported previous versions.  In this manner,
+ * a failure of the -source option to be honored would mean a pass of
+ * the test, and therefore a failure of the -source option.
+ *
+ * For JDK9 and JDK10, both support 1.7, which did not support javac's
+ * lambda construct.  So we set "-source 1.7" to compile a .java file
+ * containing the lambda construct.  javac should fail, thus showing
+ * -source to be working.  Thus the test passes.
+ *
+ *  fixVersion: JDK11
+ *      replace ./p/LambdaConstructTest.java with a missing from
+ *      JDK8, JDK9, or JDK10.  Set -source below appropriately.
