failed to resolve file: Illegal character in path in kate

[RiedleroD]

I'm using kate 22.12.2 with jdtls 1.19.0 on arch linux and the LSP server just spits a bunch of errors for file paths that have a space somewhere in them. In my case, the project folder name has a space in it.

the other errors are identical, just with different filenames.

@RiedleroD It is an upstream kate issue.
kate should send a valid URL. For instance

file:///home/riedler/Documents/schule/2223/SEW/8a%20Grand%20Prix%20von%20Monaco/src/EventBroadcaster.java

Thanks for the confirmation, I suspected so after java-language-server threw the exact same error. In fact, I filed a bug for kate and they told me it's already fixed in master.

@snjeza It seems like jdtls tries to parse rootPath as a URI too, is this intended?

Currently it is causing issues with Helix, but any LSP client sending paths that don't happen to be valid URIs (with whitespace, also backslashes for Windows) would error too.

I can open a PR for this.
