Answer 1

I'm not sure that Ignite 2.7 supports Java 11. You can try adding the Java 9+ JVM options from the documentation, though:

--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-exports=java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED
--illegal-access=permit
