ClassNotFoundException com.fasterxml.jackson.core.StreamReadConstraints [BUG]

[bartweber]

Describe the bug
Class com.fasterxml.jackson.core.StreamReadConstraints seems to be missing for opensearch-x-content-2.8.0

To Reproduce
Steps to reproduce the behavior:
In my case I was using org.opensearch.client:opensearch-rest-high-level-client:2.8.0 and did the following method call:
org.opensearch.client.indices.PutIndexTemplateRequest#source which causes a ClassNotFoundException with the following stack trace:

Caused by: java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/StreamReadConstraints
	at org.opensearch.common.xcontent.json.JsonXContent.<clinit>(JsonXContent.java:80)

Expected behavior
Should not throw ClassNotFoundException when calling org.opensearch.client.indices.PutIndexTemplateRequest#source.

Plugins
Not relevant I think.

Host/Environment (please complete the following information):
Not relevant I think.

Additional context

Hi @bartweber, Is it possible you are explicitly pulling in a version of Jackson that is lower than 2.15.x? As the StreamReadConstraints class was added in version 2.15 of jackson-core.

[bartweber]

Yes that's it @Xtansia. Sorry for the hassle. I must have been distracted while looking in this issue. We use the OpenSearch Java client (org.opensearch.client:opensearch-rest-high-level-client:2.8.0) in a Spring Boot application (org.springframework.boot:spring-boot-starter-web:2.7.13) which determines that the version 2.13.5 of jackson-core should be on the classpath while - as you explained - opensearch-rest-high-level-client needs 2.15.x or higher.

The previous version org.opensearch.client:opensearch-rest-high-level-client:2.7.0 still works i.c.w. org.springframework.boot:spring-boot-starter-web:2.7.13 (without any further adjustments).

No worries, glad you were able to find a working combination for your use case.

Hi, I am facing similar issue while we are upgrading to spring boot 3.3.2. I have analysed the dependencies and found all the jackson-core dependencies as 2.15.0 or above.

Following exceptions are occurring while running test cases:
Exception java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/StreamWriteConstraints
java.lang.NoClassDefFoundError: Could not initialize class org.opensearch.common.xcontent.json.JsonXContent

When I search for the StreamWriteConstraints class in the IDE, it is not present.

Attaching the mvn dependency tree of the project also
mvn dependencies.txt

I would Appreciate Your Help!

Thanks!

Hi,
This issue has been resolved by upgrading jackson-core dependency to version 2.17.0 . Earlier the version was 2.15.2 in which StreamWriteConstraints class was not available.

Thanks, the suggestions already available in this ticket were helpful to resolve the issue.
