Hi. Occationally I get a NPE that seems related to CamelNamespaceHandler when running under Java 7. Switching back to Java 6 I don't seem to get this problem.
The problem seems very similar to the one from this thread http://camel.465427.n5.nabble.com/Occasional-CamelNamespaceHandler-exception-when-running-with-Spring-DM-1-2-tt476984.html , however as the thread is quite old, I would like to know if anyone else has experienced this, and how to avoid it. My setup is a Grails 1.3.7 Application, using Camel 2.8.0, jdk1.7.0 I have a camelContext configured in the spring resources.xml like this: <camel:camelContext id="camel"> <camel:routeBuilder ref="eventReceiverRouteBuilder" /> </camel:camelContext> I also get the same error if I try to configure it in resources.groovy like this: xmlns camel: 'http://camel.apache.org/schema/spring' camel{ camelContext(id:"camel"){ routeBuilder(ref:"eventReceiverRouteBuilder") } } Relevant parts of stacktrace: (complete stacktrace posted here: http://pastebin.com/b88JZx6z ) 2011-08-23 14:53:20,918 [main] WARN spring.GrailsRuntimeConfigurator - [RuntimeConfiguration] Unable to perform post initialization config: /WEB-INF/spring/resources.xml org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from URL [file:./grails-app/conf/spring/resources.xml]; nested exception is java.lang.NullPointerException at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:412) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:302) at org.springframework.beans.factory.xml.XmlBeanFactory.<init>(XmlBeanFactory.java:73) ......
