Subject Re: [jira] Created: (AMQ-2083) java.io.OptionalDataException when getting a deeply nested HashMap from an ObjectMessage
Date Sat, 14 Feb 2009 18:44:15 GMT

I get this error as well but my hashmap is not deeply nested and there are no
primitive values in it.  It happen very rarely though.  Maybe 1 in 20,000
plus messages.

Any insights into fixes or workarounds available?
