    • Release Notes
    • An upstream patch applied to the Java Architecture for XML Binding (JAXB) component was found to not be thread safe. The issue was patched and the patched version of JAXB has been included in this release of JBoss Enterprise Application Platform 5.
    • Documented as Resolved Issue
    • NEW

    Description

      Fix of [1] in JAXB is not thread safe. Therefore, Map instance is returned by null at the time of high load.
      I guess that fix of [2] is required in EAP.

      [1] Map Unmarshaller modifies the map after setting it

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
