Description
VS Code extension emits an inadequate error message Lifecycle mapping "org.eclipse.m2e.jdt.JarLifecycleMapping" is not available.

Environment
- Operating System: Linux Fedora 29
- JDK version: 10.0.2
- Visual Studio Code version: 0.34.0
- Java extension version: ???
Steps To Reproduce
See https://github.com/eclipse/eclipse.jdt.ls/issues/866 for producing an internal error in Eclipse base.
Current Result
Error message: "Lifecycle mapping "org.eclipse.m2e.jdt.JarLifecycleMapping" is not available."
Expected Result
Error message: Internal error in language service (+ actionable steps for reporting / diagnosing)

Research direction
Start with the internal-error reproduction described in eclipse/jdt.ls#866 and trace where the lifecycle-mapping message is emitted in the VS Code extension. Done means the extension reports an internal language-service error with actionable steps for reporting or diagnosis instead of the misleading lifecycle-mapping message.
