Research direction
Start with GithubClient.java:103 and the executeWithRetry entry point at GithubClient.java:64, then inspect the Azure MCP release lookup that produces the Jackson MismatchedInputException. Reproduce the error using the reported IntelliJ, Windows, JDK, and plugin versions; done means the Azure MCP Server initializes without this uncaught deserialization failure.
