Runtime exception when calling expand atom on MOL

Hi,

When pushing the attached MOL through the following standardizer configuration we are getting a RuntimeException. I have been told that the compound is not valid however I would expect a checked exception to be thrown so that we have a method to gracefully deal with problem chemistry. The exception stack trace and standardizer XML config are below. Any help with this will be appreciated.

thanks

Richard

It is a bug. Thank you for reporting this problem. We will fix it as soon as possible.
