{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"`options` map modified directly","articleBody":"## Describe the bug in a sentence or two.\nWhen passing in an immutable map to `Uploader.uploadLarge` it errors out because the method [tries to update](https://github.com/cloudinary/cloudinary_java/blob/master/cloudinary-core/src/main/java/com/cloudinary/Uploader.java#L147) the same instance that was passed in to it.\nAFAICS, in most places a defensive copy is made from the `options` map, but not here. It caused issues for us as we are using the lib from Clojure interop, and by default, all the collections there are immutable.\n\n## Issue Type (Can be multiple)\n[ ] Build - Can’t install or import the SDK\n[ ] Performance - Performance issues\n[x] Behaviour - Functions aren’t working as expected (Such as generate URL)\n[ ] Documentation - Inconsistency between the docs and behaviour\n[ ] Other (Specify)\n\n## Steps to reproduce\nUse an immutable map as options for `Uploader.uploadLarge` when file is a `java.util.File`.\n\n## Versions and Libraries (fill in the version numbers)\nCloudinary Java SDK version - 1.39.0\n\n","author":{"url":"https://github.com/janosmeszaros","@type":"Person","name":"janosmeszaros"},"datePublished":"2025-07-17T13:54:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/383/cloudinary_java/issues/383"}
