Exception reported on attempting to execute a RECOVERABLE_DEFINED snippet. 

The stack can be queried by methods on Exception.
Note that in stack trace frames representing JShell Snippets,
StackTraceElement.getFileName() will return "#" followed by
the Snippet id and for snippets without a method name (for example an
expression) StackTraceElement.getName() will be the
empty string.
