v0.70 broke workspace/DidChangeConfiguration

[pbogren]

I am using jdtls through nvim-jdtls in neovim nightly where I have the following settings

local cfg = {
    cmd = { 'jdtls'},
    settings = {
        ['java.format.settings.url'] =  '/path/to/style.xml',
        ['java.format.settings.profile'] = 'MyStyle',
    ...
}

cfg.on_init = function(client, _)
    client.notify('workspace/didChangeConfiguration', { settings = client.config.settings })
end

This works fine with v0.69 but with v0.70 I get the following error

EDIT: Just to clarify, I reverted back to v0.69 to verify that the error was introduced after upgrading to v0.70 and it still works in the previous version which should rule out other factors.

@MMfood could you try

 ['java.format.settings.url'] = 'file:///path/to/style.xml',

[pbogren]

@snjeza Yes, that worked! Thanks, that was quick!

Is that a bug or a feature?

[snjeza]

@MMfood It is a bug.

[pbogren]

ok, good to know. Also, let me take this opportunity to thank you and others for your work on this project!
