### Fatal error compiling: java.lang.ExceptionInInitializerError Right after changing the JAVA version from `10` to `20` in the [pom.xml](/YNaMi/pom.xml) file, `mvn clean compile` started failing with fatal error.### Fix Fix for this problem in my setup/environment was just to set the latest version (i.e. `1.18.28`) for the `lombok` maven plugin in the [pom.xml](/YNaMi/pom.xml) file.Click here for stacktrace

So fix for this problem in my setup/environment was just to set the `jvmArguments` with `add-opens` in the `spring-boot-maven-plugin` maven plugin in the [pom.xml](/YNaMi/pom.xml) file. ```xml ``` But don't forget to add the following to VM options if running this application from IDE: `--add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.reflect=ALL-UNNAMED` But since the spring boot upgrade, seems like we don't need to set them in the VM options nor in the `spring-boot-maven-plugin` in pom.xml file. </details> </blockquote> org.springframework.boot spring-boot-maven-plugin --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.reflect=ALL-UNNAMED Click to see details of InaccessibleObjectException
### Application run failed: java.lang.reflect.InaccessibleObjectException Right after fixing the issues with compiling the project, `mvn clean failsafe:integration-test -Pit` started failing with `Application run failed` with `InaccessibleObjectException` and similar exceptions.### Fix I guess, since Java 17, we need to add the following `add-opens` to VM options in order to use reflection. So fix for this problem in my setup/environment was just to set the `argLine` with `add-opens` in the `maven-failsafe-plugin` maven plugin in the [pom.xml](/YNaMi/pom.xml) file. ```xmlClick here for stacktrace
```exception java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.findLoadedClass(java.lang.String) accessible: module java.base does not "opens java.lang" to unnamed module `````` NOTE the use of `-D` with `-D${testArgLine}` as without `-D`, we'll end up with `java.lang.ClassNotFoundException: ${testArgLine}` Apparently, the use of `-D` with `-D${testArgLine}` has fixed the `java.lang.ClassNotFoundException: ${testArgLine}` error, but it has caused another problem, and that is the reason the jacoco is not able to generate `it.exec` data file. So, we'll have to use `@` for placeholder replacement instead of `-D$` or just `$` for the proper jacoco results. But don't forget to add the following to VM options if running the integration tests from IDE: ``` --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.text=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.reflect=ALL-UNNAMED --add-opens java.desktop/java.awt.font=ALL-UNNAMED ``` But since the spring boot upgrade, seems like we just need to set `--add-opens java.base/java.lang=ALL-UNNAMED` in the VM options and the following in pom.xml file: ```xml org.apache.maven.plugins maven-failsafe-plugin ${maven-surefire-plugin.version} --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.text=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.reflect=ALL-UNNAMED --add-opens java.desktop/java.awt.font=ALL-UNNAMED -D${failsafe.jacoco.exec.file.name.arg} it.pk.lucidxpo.**/*IntegrationTest.class ${skip.integration.tests} ${ignore.test.failures} ${integration.tests.results.directory} ``` #### How do I use properties set by other plugins in argLine? Maven does property replacement for `${...}` values in pom.xml before any plugin is run. So Surefire would never see the place-holders in its argLine property. Since the Version 2.17 using an alternate syntax for these properties, `@{...}` allows late replacement of properties when the plugin is executed, so properties that have been modified by other plugins will be picked up correctly. org.apache.maven.plugins maven-failsafe-plugin ${maven-surefire-plugin.version} @{failsafe.jacoco.exec.file.name.arg} --add-opens java.base/java.lang=ALL-UNNAMED it.pk.lucidxpo.**/*IntegrationTest.class ${skip.integration.tests} ${ignore.test.failures} ${integration.tests.results.directory} Click to see details of NoClassDefFoundError: javax/xml/bind/JAXBException
