/*
 * In order to test whether or not the -source option is working
 * correctly, this test tries to parse source code that contains
 * a feature that is not available in at least one of the currently
 * supported previous versions.
 *
 * Parsing such code should be expected to fail; if the action
 * passes, that means the -source option is (incorrectly) ineffective.
 *
 * Additional actions are performed to ensure that the source
 * provided is valid for the current release of the JDK.
 *
 * As support for older versions of the platform are dropped, the
 * source code (currently p/LambdaConstructTest.java) will need to
 * be updated with a more recent feature.
