Fatal error compiling: java.lang.ExceptionInInitializerError

Right after changing the JAVA version from 10 to 20 in the 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 file.

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 jvmArguments with add-opens in the spring-boot-maven-plugin maven plugin in the pom.xml file.
<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        
        <jvmArguments>
            --add-opens java.base/java.lang=ALL-UNNAMED
            --add-opens java.base/java.lang.reflect=ALL-UNNAMED
        </jvmArguments>
    </configuration>
</plugin>
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.

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 file.
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>${maven-surefire-plugin.version}</version>
    <configuration>
        
        <argLine>
            --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${failsafe.jacoco.exec.file.name.arg}
        </argLine>
        <test>it.pk.lucidxpo.**/*IntegrationTest.class</test>
        <skipTests>${skip.integration.tests}</skipTests>
        <testFailureIgnore>${ignore.test.failures}</testFailureIgnore>
        <reportsDirectory>${integration.tests.results.directory}</reportsDirectory>
    </configuration>
</plugin>
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:
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>${maven-surefire-plugin.version}</version>
    <configuration>
        
        <argLine>
            @{failsafe.jacoco.exec.file.name.arg}
            --add-opens java.base/java.lang=ALL-UNNAMED
        </argLine>
        <test>it.pk.lucidxpo.**/*IntegrationTest.class</test>
        <skipTests>${skip.integration.tests}</skipTests>
        <testFailureIgnore>${ignore.test.failures}</testFailureIgnore>
        <reportsDirectory>${integration.tests.results.directory}</reportsDirectory>
    </configuration>
</plugin>
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.

Fix

Fix for this problem in my setup/environment was just to set the latest version (i.e. 2.3.1) for the jaxb-api maven dependency as well as changing its scope from test to default in the pom.xml file.

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>${jaxb.api.version}</version>
</dependency>

So, now mvn clean spring-boot:run is happy and the server is up and running without any exceptions.

Fix

Fix for this problem in my setup/environment was just to add the net.bytebuddy:byte-buddy maven dependency in test scope in the pom.xml file.

<dependency>
    <groupId>net.bytebuddy</groupId>
    <artifactId>byte-buddy</artifactId>
    <version>1.14.5</version>
    <scope>test</scope>
</dependency>

So, now all the unit as well as integration tests are running and passing without any exceptions.
