Start in GithubClient.java at getLatestAzureMcpRelease (line 103), then read executeWithRetry (line 64) and the GithubRelease type referenced by the exception. Reproduce the Azure MCP Server initialization failure on the reported IntelliJ setup and verify that release data is handled without the Jackson deserialization error.
