Open IntelliJ IDEA\r\n2. Plugin is installed\r\n3. Create a new project with JDK 8\r\n4. Add a class LambdaVarExample  (see below)\r\n5. Run test generation\r\n6. Repeat 3-5 steps for a project with JDK 11\r\n\r\n```\r\nimport java.util.function.Predicate;\r\n\r\npublic class LambdaVarExample {\r\n\r\n    private Predicate\u003c? super String\u003e byCondition = l -\u003e l.contains(\"b\");\r\n\r\n    public void runTest(String input) {\r\n        if (byCondition.test(input)) {\r\n            firstScenario();\r\n        } else {\r\n            secondScenario();\r\n        }\r\n    }\r\n\r\n    private void firstScenario() {\r\n        System.out.println(\"1\");\r\n    }\r\n\r\n    private void secondScenario() {\r\n        System.out.println(\"2\");\r\n    }\r\n\r\n}\r\n```\r\n\r\n**Expected behavior**\r\n\r\n5-6. Tests are supposed to be generated without errors.\r\n\r\n**Actual behavior**\r\n\r\nAn error test is generated with information about...\r\n5. JDK 8 - ClassNotFoundException in concrete...\r\n6. JDK 11 - InaccessibleObjectException in constructCompositeModel.\r\n\r\n**Visual proofs (screenshots, logs, images)**\r\n\r\n5.
