    When a flow which contains a camel-validation endpoint is started, the XSD schemas are not loaded until the first request comes in and the camel-validation endpoint is first hit. If two requests come in simultaneously, the initialization will be performed twice, at the same time. It seems that SchemaFactory is not thread-safe, so this results in the following exception: 10:38:20,860 | ERROR - org.apache.camel.processor.DeadLetterChannel - org.apache.camel.processor.Logger - Failed delivery for exchangeId: ID-ATOS-B624 E47AF0/3211-1240562892751/0-11.

For more info: http://www.nabble.com/Concurrency-Issue-with-camel-validation-td23213294.html Is it possible to backport the fix to 1.4?
