Probably this isn't a small effort. Today I looked into implementing an IDiagnosticsParticipant. Following the implementation of the XSDDiagnosticsParticipant, I'm also stumbling over Xerces implementation classes, such as the XMLErrorReporter,...

This first PR implements your suggestions for moving the code around. I suppose we can merge it independently. Afterwards, I'd have a look at hiding the Xerces-dependencies.

I've written some wrapper code as part of liquibase-lsp here: https://github.com/Treehopper/liquibase-lsp/tree/develop/org.eclipse.lemminx.api/src/main/java It certainly only covers a small part of the API, and it is not a well thought out implementation,...

I had an idea for approaching this in a way that allows solving the problem iteratively, measurably and at the same time, safe-guard against re-introducing new Xerces dependencies. Given that...

I can confirm your observation. I'm compiling it with 14 myself. This is less an immediate issue, and more of a "timebomb". Steps to reproduce the issue: - set maven-compiler-plugin...

@romani Sorry for the confusion. Maybe I should've emphasized in the description that the opening dialog is completely _invisible_, instead of just mentioning it in the title. For anybody who...

I can confirm that it works with both records and pattern matching. Kudos @bsideup ! The only problem I had is that jitpack is not keeping those branch-artifacts around for...

Looking forward to it! Hope #30 makes wrapping it up a bit easier. I could also add something for _@Desugar_. Let me know.
