tutorial example breaks as soon as you add module-info.java

[sdyura]

I downloaded https://github.com/arangodb/arangodb-java-driver/tree/main/tutorial/maven

and added my projects module-info.java, and the example stopped working

arangodb-java-driver-demo.zip

Thanks for reporting, @sdyura

This caused by FasterXML/jackson-core#1340 and needs to be fixed and backported in Jackson core.

For the moment, to work-around either:

• do not require Jackson in your module-info.java (and remove related code usages), or
• use the shaded Java driver (com.arangodb:arangodb-java-driver-shaded) and the shaded Jackson classes (from package com.arangodb.shaded.fasterxml.jackson), or
• use the shaded Java driver (com.arangodb:arangodb-java-driver-shaded) and the Jackson JSON serde (com.arangodb:jackson-serde-json) and manually configure the JSON serde:

        JsonFactory jf = new JsonFactory();
        JacksonUtils.tryConfigureJsonFactory(jf);
        ObjectMapper mapper = new ObjectMapper(jf);
        JacksonSerde serde = JacksonSerde.create(mapper);
  
        arangoDB = new ArangoDB.Builder()
                // ...
                .serde(serde)
                .build();

Fixed in Jackson 2.18 and released in ArangoDB Java driver 7.10.0: https://github.com/arangodb/arangodb-java-driver/releases/tag/v7.10.0

Feel Free to reopen in case of further problems.
