Start with GithubClient.java at downloadToFile around line 123 and reproduce the Azure MCP Server initialization failure using the reported IntelliJ, Windows 11, JDK, and plugin versions. Trace the premature end-of-content-length failure during the download, then verify that initialization completes without the uncaught exception.
