@DrXala I am not quite sure that it is related to reflection access, it looks like several processes tried to open the same database. Are you sure that no Java processes were running at the same time?

I get an illegal reflective access warning, too. running orientdb 2.2.28 with java zulu 9.0.0.15.

@ancho warning will be fixed during next releases. It is not critical and does not affect functionality.

@DrXala Could you provide information which I asked you above ?

laa picture laa on 10 Oct 2017

@laa I'm not sure and my dev team work with my installation. So I can't to retry with Java 9 now.

DrXala picture DrXala on 10 Oct 2017

You've got two issues here.

The "Illegal reflective access" warning is telling you that code in com.orientechnologies.common.directmemory.OByteBufferPool is hacking into a JDK internal method and this will break once the JDK dials up its encapsulation.

The second is probably a reflection anti-pattern, the code in com.orientechnologies.common.util.OMemory is trying to invoke a method on the JDK internal class, it should be invoking it on the public interface. It may be that it's invoking getMethod on the implementation class rather than the interface.

With openjdk Zulu build 9.0.1.3+11 and orientdb 2.2.30 only the OByteBufferPool warning is left.
