Filipp Shergalis commented on IGNITE-24559:
-------------------------------------------
[~ascherbakov]
Encountered the same issue in QA tests that accidentally restarted node with
Java 11 instead of Java 17. Caused by *ByteBuffer* in ScaleCube's
{*}GetMetadataResponse{*}:
{code:java}
final class GetMetadataResponse implements Externalizable {
private static final long serialVersionUID = 1L;
/** Target member with metadata. */
private Member member;
/** Cluster member metadata. */
private ByteBuffer metadata;{code}
This causes *DefaultUserObjectMarshaller* to load java internal classes
descriptors when deserialising corresponding *ScaleCubeMessage*
> The cluster fails to init if nodes are running on different JDK versions
