We have reproduced the following:
1. V8ScriptEngine collects error details only when the thrown object is an Error instance.
2. V8ScriptEngine does not collect error details for syntax errors.
Comments: Fixed in [Version 5.3.3](https://clearscript.codeplex.com/SourceControl/changeset/caa2c86e14b1c84e38fa3aedd34e0420aef45209).
