Technically yes, but it's discouraged because mutability introduces race condition risks whenever more than one thread is involved. Scoped values themselves are not tied to multi-threading, so binding a mutable object is safe only if no new thread is spawned within the task's scope; otherwise developers must manage race conditions manually. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Can I bind a mutable object to a ScopedValue in Java? Yes, it is technically possible to bind a mutable object to a ScopedValue, but it is discouraged. Mutability introduces race condition risks whenever more than one thread can access the object. Binding a mutable value is only safe when the task using the scoped value guarantees no new thread is created within its scope; otherwise, race conditions must be managed manually. _Developers weighing safe concurrency patterns in Java can find practical breakdowns like this on daily.dev._ ## Similar posts on daily.dev - [Scoped Values: Why I Banned ThreadLocal in Exeris](https://daily.dev/posts/scoped-values-why-i-banned-threadlocal-in-exeris-hook5lrg1) · Foojay.io · 5 upvotes · 0 comments - [On the Boundaries of Final](https://daily.dev/posts/on-the-boundaries-of-final-ilcxzezrq) · Inside Java · 0 upvotes · 0 comments - [Stop Using Shared Mutable State — Embrace Immutability for Safer Code](https://daily.dev/posts/stop-using-shared-mutable-state-embrace-immutability-for-safer-code-r2wrr0tjn) · Javarevisited · 1 upvotes · 0 comments --- Tags: [#java](https://daily.dev/tags/java) [View this post on daily.dev](https://daily.dev/posts/can-you-bind-mutable-objects-to-scopedvalues---cracking-the-java-coding-interview-javacoding-q0gjoeq7x) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Can you bind mutable objects to ScopedValues? - Cracking the Java Coding Interview #javacoding","url":"https://daily.dev/posts/can-you-bind-mutable-objects-to-scopedvalues---cracking-the-java-coding-interview-javacoding-q0gjoeq7x","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/can-you-bind-mutable-objects-to-scopedvalues---cracking-the-java-coding-interview-javacoding-q0gjoeq7x"},"datePublished":"2026-10-02T10:04:31.982Z","dateModified":"2026-10-02T10:04:44.905Z","description":"A short Q&A explains whether mutable objects can be bound to Java's ScopedValues.
