Describe the Bug
Install the “Extension Pack for Java
0.29.2” in Cursor, which includes Language Support for Java™ by Red Hat v1.43.1. After opening a Java Maven project, when attempting to chat with the agent, the agent either gets stuck while editing files or outputting text. Simultaneously, the Cursor process in Win10 Task Manager shows consistently high CPU usage, appearing to enter an infinite loop.
I used the Start Extension Bisect command, and the report indicated the issue was with Language Support for Java™ by Red Hat.
Steps to Reproduce
- Install the Extension Pack for Java
- Open a Java Spring Boot Maven Project
- Language service running
- Chat with the agent
Expected Behavior
agent working normally
Operating System
Windows 10/11
