Can you please let me know what can be the reason for it and how can I avoid this issue ?

Suspected Code

ObjectMapper mapper = new ObjectMapper();
mapper.readTree(new File(path)

You have a version mismatch between jackson-core and jackson-databind: latter has higher minor version than former -- so version of jackson-core does not have class StreamConstraintsException.
Make sure they have same minor version; or (if you must), jackson-core has higher (that often works) but not lower version.

These are the version in lib folder, Am I missing anything here?

[JooHyukKim]

@VSJNotgeek plz refer to what has been answered above.

[JooHyukKim]

Lib folder contains versions as required. Maybe it's possble the jars are not even used at run time.

[cowtowncoder]

Versions of Smile and YAML format modules are awfully old and should be aligned, but those are not root causes of the issue here.

[VSJNotgeek]

It is possible to understand which JAR is being used is being used at runtime ?

[JooHyukKim]

Yes, though it depends on your environment --Build tool, IDE, etc... but out of scope of what you should get help from here

[VSJNotgeek]

Thanks @cowtowncoder @JooHyukKim

[JooHyukKim]

I am sorry I couldn't help more 🙏🏼
Debugging the runtime itself is a whole other subject.
Wish you best!

This error means you have a version mismatch between jackson-core and jackson-databind. StreamConstraintsException was added in Jackson 2.15.0 (as part of the default stream constraints feature). Your databind is ≥2.15 but your jackson-core is <2.15.

Check your dependency tree:

mvn dependency:tree -Dincludes=com.fasterxml.jackson

You'll likely see something like:

com.fasterxml.jackson.core:jackson-databind:2.15.2
com.fasterxml.jackson.core:jackson-core:2.14.3  ← old

Fix: Align all Jackson versions:

<properties>
    <jackson.version>2.15.3</jackson.version>
</properties>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson.version}</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${jackson.version}</version>
</dependency>

If a transitive dependency pulls in an older jackson-core, exclude it:

<dependency>
    <groupId>some.library</groupId>
    <artifactId>some-artifact</artifactId>
    <exclusions>
        <exclusion>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>

For Gradle: implementation("com.fasterxml.jackson.core:jackson-core:2.15.3") and use constraints or strictly to enforce version alignment.

Even better: use jackson-bom BOM to get consistent version for all components: https://mvnrepository.com/artifact/com.fasterxml.jackson/jackson-bom
