Apache Ignite support for java 17

Question

Does apache ignite 2.14.0 work with java 17?

Tried running a java 17 application which uses apache ignite 2.14.0 and this error occured: Error while running java 17 application using which uses apache 2.14.0

Answer 1

Yes, it does. As the doc says, use the following JVM options:

--add-opens=jdk.management/com.sun.management.internal=ALL-UNNAMED \
--add-opens=java.base/jdk.internal.misc=ALL-UNNAMED \
--add-opens=java.base/sun.nio.ch=ALL-UNNAMED \
--add-opens=java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED \
--add-opens=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED \
--add-opens=java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED \
--add-opens=java.base/java.io=ALL-UNNAMED \
--add-opens=java.base/java.nio=ALL-UNNAMED \
--add-opens=java.base/java.util=ALL-UNNAMED \
--add-opens=java.base/java.lang=ALL-UNNAMED

Or, use ignite.sh / ignite.bat scripts, which do this for you.

Here's the spring-boot-maven-plugin JVM arguments configuration I'm using with Ignite & Java17.

                 <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <jvmArguments>
                            --add-opens=jdk.management/com.sun.management.internal=ALL-UNNAMED
                            --add-opens=java.base/jdk.internal.misc=ALL-UNNAMED
                            --add-opens=java.base/sun.nio.ch=ALL-UNNAMED
                            --add-opens=java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED
                            --add-opens=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED
                            --add-opens=java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED
                            --add-opens=java.base/java.io=ALL-UNNAMED
                            --add-opens=java.base/java.nio=ALL-UNNAMED
                            --add-opens=java.base/java.util=ALL-UNNAMED
                            --add-opens=java.base/java.lang=ALL-UNNAMED
                        </jvmArguments>
                    </configuration>
                </plugin>
