> Stack Trace
> Any file containing a string with '\8' or '\9' in it will cause an IllegalArgumentException whenever ASTParser executes on it. This prevents the JavaScript editor from being initialized, preventing normal opening of the file.
> '\#' in pre ES5 is used to denote an octal escape sequence, and so \8 and \9 are indeed invalid, but this should be reported as an error in the file. 
> The error is thrown in org.eclipse.wst.jsdt.core.util.JsStringScanner#scanEscape() and is not caught.
> To reproduce: create a new JavaScript file, add the line `var x = "\8"` to it, 
> and attempt to save the file.
