This looks like an exception from the TinkerPop serialization code, where SQL Workbench is using passing an AtomicLong (as opposed to a regular Long), which is causing an exception because it is not a serializable type. I have this on my backlog to look at and will try to take a look soon.
I looked into this in depth. This issue only exists when using OpenJDK 17 and TinkerPop 3.4.8.
So the solution seems to be to upgrade the JDBC Driver (and sql-gremlin) to 3.5.2.
I need to do proper testing before committing this change though, so I have made this ticket to track that since this exact issue was reported somewhere else as well.
See #159 going forward.
A workaround would be for you to use a different JDK or alternatively you could likely inject a different serialization protocol into TinkerPop. Please let me know if you need assistance with the latter, as I can show you how it's done.
Describe the bug
I have the driver configured in SQL Workbench and when I try a simple query
select count(*) from File;
I get back error:
An error occurred when executing the SQL command: select count(*) from File
Error occurred during schema collection. 'java.util.concurrent.ExecutionException: shadow.io.netty.handler.codec.EncoderException: shadow.org.apache.tinkerpop.gremlin.driver.exception.ResponseException: An error occurred during serialization of this request [RequestMessage{, requestId=e3f911dc-8a81-49f0-b7b8-5f8ee32718de, op='bytecode', processor='traversal', args={gremlin=[[], [V(), label(), dedup()]], aliases={g=g}}}] - it could not be sent to the server - Reason: shadow.org.apache.tinkerpop.gremlin.driver.ser.SerializationException: java.lang.IllegalArgumentException: Unable to create serializer "shadow.org.apache.tinkerpop.shaded.kryo.serializers.FieldSerializer" for class: java.util.concurrent.atomic.AtomicLong'. 1 statement failed.
Execution time: 4.71s
To my understanding this should be a supported query type
Steps to Reproduce
Expected behavior
Expected SQL Workbench to reply
66400
as that is how many vertices with label "File" there are in my graph.Screenshots
