completionItem/resolve fails with NullPointerException

[TrevCraw]

This behaviour was observed while using the latest release version (0.8.0) of the Tools for MicroProfile VS Code extension with a Maven project configured with MP 5.0 (also tried with MP 4.1). When typing ctrl + space to pull up a list of snippets, the below NPE occurs, but the snippets can still be selected.

Duplicate of redhat-developer/vscode-microprofile#161 which has been fixed.

I suggest that you swith to vscode-microprofile prerelease and you should avoid having this error.
