Migrate to lsp4j 0.7.x

[fbricon]

@NikolasKomonen wanna give it a try? now that you're familiar with 0.7.1 ;-)

[NikolasKomonen]

Yeah, sounds good.

lsp4j changelog:
* Setters and constructors of protocol classes throw IllegalArgumentException if given null for properties marked with @NonNull

Hope there wont be many issues with this one :)

[fbricon]

@NikolasKomonen actually migration to 0.7 should be covered by #925 already. So we can wait for @kittaakos's update of that PR

Yeah, I do not like this change either. If you find the new behavior inconvenient, please file an issue in LS4J.

So we can wait for @kittaakos's update of that PR

Please note, according to the plans, there will be a 0.7.2 release, so that the textDocument/callHierarchy is in sync with the proposed LSP change.

[fbricon]

@kittaakos cool. do you have a timeframe for that?

[kittaakos]

do you have a timeframe for that?

Did you mean wrapping up the call hierarchy implementation? I am a little bit busy with other things, but I will look into the required changes on of the evenings. How urgently would you like to see the textDocument/callHierarchy on the master? :)

[fbricon]

nothing urgent. Just so I have an idea in which release to target the feature.
I'm just eager to play with it in vscode ;-)

@fbricon I tried this one as my first commit :-)
