The README.md links for "Java MCP client" to the url "modelcontextprotocol.github.io/java-sdk/client" which leads to a 404 on GitHub.
I assume the correct URL is supposed to be
modelcontextprotocol.github.io/java-sdk/blob/main/docs/client.md or java.sdk.modelcontextprotocol.io/latest-snapshot/client ?
The same applies to the link on "Java MCP Server" and "Java Dependencies /BOM".
