# devopsgym / codegen__spotbugs__spotbugs-2874 - taskset: [devopsgym](https://harnessreport.com/tasks/devopsgym.md) - difficulty: hard - category: code-generation - language: - runnable from the site: no - agent timeout: 3000s ## Results by harness _none yet_ ## Instruction ``` This is a code generation task. You are expected to write working code that solves the described problem. <issue> There are some false positives and negatives of NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE related to various combinations of custom nullables and null checks. One of them is especially nefarious, as it relies solely on the formatting of the source code. See the example project which reproduces the issues. [Example project](https://github.com/davidburstromspotify/spotbugs-checknotnull-bug/blob/master/src/main/java/Example.java) </issue> Focus on implementing the required functionality correctly and efficiently. Treat this as a programming challenge. You are not allowed to read git history. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
