Getting above error while using ConnectionPool. For connectionPath I'm trying :

public static final PaddedEPath connectionPath = new EPath.PaddedEPath(new PortSegment(1, new byte[] {(byte) 0}));
public static final EPath.PaddedEPath connectionPath = new EPath.PaddedEPath(Collections.emptyList());

Still getting the same error.

Sounds similar to this issue, where the problem ending up being that they were not configuring a vendor ID.

[prasenjith-altizon]

Yes. It worked after I changed vendorId to 1.
Thank You @kevinherron
