Logs (optional)

!ENTRY org.eclipse.lsp4e 2 0 2026-01-27 09:58:42.354
!MESSAGE [LS:GitHub Copilot Language Server][Warning]	[McpAutoApproveService] Invalid McpAutoApproveService config, resetting to empty undefined

!ENTRY org.eclipse.lsp4e 2 0 2026-01-27 09:58:42.377
!MESSAGE [LS:GitHub Copilot Language Server][Warning]	[default] Policy watcher not available - continuing without policy watching: Unsupported platform

!ENTRY org.eclipse.lsp4e 1 0 2026-01-27 09:58:42.377
!MESSAGE [LS:GitHub Copilot Language Server][Info]	[GithubAvailableEmbeddingTypes] Could not find any available embedding types. Error: noSession

Expected behavior

1. No warning is logged
2. If a warning is shown, it has at least some stack attached

Actual behavior

1. Warnings are reported during many Eclipse tests
2. Warnings have no context, no idea how to "fix" them

The problem is that we have tests check for unexpected errors and warnings and now every time tests start (~30 times during our automated tests) we have multiple warnings reported as test failures. Our customers are also not accepting any warnings or errors in the logs "by default" in a freshly installed application.

This is a blocker for us for 0.15.0 use.

Additional information

No response

Start by reproducing the Eclipse startup with Copilot 0.15.0 and inspect the three logged messages from org.eclipse.lsp4e: McpAutoApproveService, policy watcher, and available embedding types. Check the automated tests that treat unexpected warnings as failures. Done means startup and repeated test runs no longer emit these uncontextualized warnings, or each remaining warning has useful context.
