The error is thrown from here due to /Users/t/OneDrive - company/code/java_global.prefs cannot be parsed to a URI.

Then it will be dealt as a file path. In your case, are the settings in the java_global.prefs file take effect?

@jdneo

Oh I just noticed, they take effect, but the exception is a bit confusing and cluttering

[rgrunber]

Would @snjeza 's PR from #2451 help with this ?

[jdneo]

Seems not. #2451 is to check invalid url value. While in this case, user's url is a valid value.

The exception is thrown because the server will first try to parse a windows file path string to a URL. After failure, the server fallbacks to treat it as a file path. So it's still working finally.

Still occurs. Quite annoying in 2025 to not be able to use spaces in paths.
