--------------------------------
Summary: JAXB Coder is not thread safe
Key: BEAM-358
URL: https://issues.apache.org/jira/browse/BEAM-358
Project: Beam
Issue Type: Bug
Reporter: Thomas Groh
Marshaller and Unmarshaller are cached for reuse in an instance variable. These
objects are not thread safe
(http://stackoverflow.com/questions/7400422/jaxb-creating-context-and-marshallers-cost),
so they should be accessed in a single-threaded manner, either via use of a
ThreadLocal or creating a new instance in calls to encode/decode.
