      Description

      This was an issue in Tuscany 1.x and is likely an issue in the 2.x code as well. The fix in 1.x was to synchronize schema loading across all XSDModelResolvers.

      Starting multiple applications simultaneously can lead to an
      exception such as:

      org.apache.ws.commons.schema.XmlSchemaException: Schema name conflict in collection. Namespace: http://my.namespace
