> Project: Sling
> Issue Type: Bug
> Components: Scripting

> The
> {{org.apache.sling.scripting.sightly.impl.compiler.frontend.SightlyParserErrorListener}}
> handles ANTLR parsing errors, in order to provide more detailed and easier
> to understand error reporting for Sightly scripts.
> For the cases when ANTLR doesn't provide a {{RecognitionException}}, although
> the listener still throws an error, the error is because the
> {{SightlyParsingException}} is instantiated with a {{null}} cause.
