Run the 'utbot' project in IntelliJ Idea 2022.3 Ultimate\r\n2. Install [plugin built from unit-test-bot/rc2023.3 branch](https://github.com/UnitTestBot/UTBotJava/actions/runs/4487896210)\r\n3. Create a new project with JDK 17 (f.i. Maven)\r\n4. Add the following dependency to pom.xml:\r\n\r\n```xml\r\n        \u003cdependency\u003e\r\n            \u003cgroupId\u003eorg.slf4j\u003c/groupId\u003e\r\n            \u003cartifactId\u003eslf4j-api\u003c/artifactId\u003e\r\n            \u003cversion\u003e1.7.36\u003c/version\u003e\r\n        \u003c/dependency\u003e\r\n```\r\n\r\n5. Copy-paste `mixed\\LoggerExample.java` into it\r\n6. _**Generate and Run**_ tests with mocks + static mocks (default settings)\r\n\r\n**Expected behavior**\r\n\r\nTests classified as Successful should pass.\r\n\r\n**Actual behavior**\r\n\r\n3 successful executions generated by Symbolic engine - fail.\r\nThe following error is produced by `UtUtils.getStaticFieldValue()` :\r\n\r\n**java.lang.reflect.InaccessibleObjectException: Unable to make private native java.lang.reflect.Field[] java.lang.Class.getDeclaredFields0(boolean) accessible: module java.base does not \"opens java.lang\" to unnamed module @5afa04c**\r\n\r\n**Visual proofs (screenshots, logs, images)**\r\n\r\n~~~java\r\n    @Test\r\n    @DisplayName(\"loggerUsage: -\u003e return 2\")\r\n    public void testLoggerUsage_Return2() throws ClassNotFoundException, IllegalAccessException, NoSuchFieldException {\r\n        org.mockito.MockedStatic mockedStatic = null;\r\n        try {\r\n            Class loggerExampleClazz = Class.forName(\"org.utbot.examples.mixed.LoggerExample\");\r\n            Logger prevLogger = ((Logger) getStaticFieldValue(loggerExampleClazz, \"logger\"));\r\n            try {\r\n                Logger loggerMock = mock(Logger.class);\r\n                (when(loggerMock.isDebugEnabled())).thenReturn(false);\r\n                setStaticField(loggerExampleClazz, \"logger\", loggerMock);\r\n                mockedStatic = mockStatic(org.slf4j.LoggerFactory.class);\r\n                (mockedStatic.when(() -\u003e org.slf4j.LoggerFactory.getLogger(any(Class.class)))).thenReturn(loggerMock);\r\n                LoggerExample loggerExample = new LoggerExample();\r\n\r\n                int actual = loggerExample.loggerUsage();\r\n\r\n                assertEquals(2, actual);\r\n            } finally {\r\n                setStaticField(LoggerExample.class, \"logger\", prevLogger);\r\n            }\r\n        } finally {\r\n            mockedStatic.close();\r\n        }\r\n    }\r\n~~~\r\n\r\n**Environment**\r\n\r\nIntelliJ IDEA 2022.3.3 Ultimate\r\nJDK 17\r\n\r\n**Additional context**\r\n\r\nThe same tests generated in UTBotJava project pass.\r\nThat happens because of specially added list of \"--add-opens\" keys to jvmArgs.\r\n\r\nWhen the following keys are added to the test run configuration in the new project - the tests pass.\r\n`-ea  --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.reflect=ALL-UNNAMED`\r\n","author":{"url":"https://github.com/alisevych","@type":"Person","name":"alisevych"},"datePublished":"2023-03-23T14:52:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/2026/UTBotJava/issues/2026"}
