+To use `withEnvironment` with JDK17+ you need to add `--add-opens=java.base/java.util=ALL-UNNAMED`
+and `--add-opens=java.base/java.lang=ALL-UNNAMED` to the arguments for the JVM that runs the tests.
 
 If you run tests with gradle, you can add the following to your `build.gradle.kts`:
 
 ```kotlin
 tasks.withType<Test>().configureEach {
-    jvmArgs("--add-opens=java.base/java.util=ALL-UNNAMED")
+    jvmArgs("--add-opens=java.base/java.util=ALL-UNNAMED", "--add-opens=java.base/java.lang=ALL-UNNAMED")
 }
