Melan Jayasinghage commented on IGNITE-8618:
--------------------------------------------
I am using Ignite 2.5.0 and would like to run it on Java 10. What should be the
JVM_OPTS for Java 10 compatibility ? I am using the same options as Java 9 as
below..
{code:java}
${JAVA_HOME}/bin/java -version 2>&1 | grep -qE 'java version "(9|10).*"' && {
JVM_OPTS="--add-exports java.base/jdk.internal.misc=ALL-UNNAMED \
--add-exports java.base/sun.nio.ch=ALL-UNNAMED \
--add-exports java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED \
--add-exports jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED \
--add-modules java.xml.bind \
${JVM_OPTS}"
} || true{code}
Ignite working fine but showing following warning on startup, is it safe to
ignore ?
{code:java}
