xsd:nillable element causes endless loop on JSON serialization of JAXB object
-----------------------------------------------------------------------------
Key: TUSCANY-3444
URL: https://issues.apache.org/jira/browse/TUSCANY-3444
Project: Tuscany
Issue Type: Bug
Reporter: Kelvin Goodson
When returning an element of type JAXB generated type Plan, generated using the
schema below, an endless loop is entered that eventually creates an out of
memory error (see below also). --
Removing the nillable from the dueDate element of WorkItem fixes the problem.
