IpInfo*Resolver classes only handle a specific set of exception types. Unknown exceptions bubble up, leading to processing failure.
Extend exception handling to cover all types of exceptions.
Description
When an IP address cannot be resolved against the IPInfo DB, we may receive a com.maxmind.db.DeserializationException from IPinfoIPLocationDatabaseAdapter.
This may occur in 2 places:
MaxmindDataAdapter: this class handles any exceptions in lookup.
IpInfoIpAsnResolver and IpInfoLocationResolver: these classes only handle a subset of exception types, resulting in an unexpected exception and failure to process messages when an unknown exception is encountered.
Motivation and Context
This affects all versions that support IPInfo DBs, i.e. 5.1 and up.
