internalError: Error running rule requirePaddingNewLineAfterVariableDeclaration

[Arcanemagus]

When running jscs v3.0.3 against this file:

foo.js:

let foo = false;
function bar($foobar) {}

With this configuration:

.jshintrc:

{
  "disallowUnusedParams": true,
  "requirePaddingNewLineAfterVariableDeclaration": true
}

I get the following error in the output:

internalError: Error running rule requirePaddingNewLineAfterVariableDeclaration: This is an issue with JSCS and not your codebase.

It seems the issue with requirePaddingNewLineAfterVariableDeclaration is causing the code issue reported by disallowUnusedParams to be reported on the wrong line:

A folder with a minimal reproduction case is included here: linter-jscs_GH249-1.zip

If there is any further information you need just let me know.

Note that this was initially filed here.

There is also a bug with the following:
.jscsrc:

{
  "disallowPaddingNewlinesInBlocks": true,
  "requirePaddingNewLineAfterVariableDeclaration": true
}

foo.js:

let foo = 42;
function bar() {

  let foobar = 42;
}

I'm assuming that the root cause is the same as this one since it requires the requirePaddingNewLineAfterVariableDeclaration rule as well, but if you want this filed as a separate bug just let me know.
