NPE when attempting to expose JaxWs Port Proxy via mbean exporter [SPR-7011]

[spring-projects-issues]

Karl Palsson opened SPR-7011 and commented

Not critically important, but if you try and use the MBean exporter (org.springframework.jmx.export.MBeanExporter) to export a web services client (JaxWsPortProxyFactoryBean) then you get an NPE

MBeanExporter.adaptMBeanIfPossible() gets a null back from AopUtils.getTargetClass(), (probably right?)
then JmxUtils.getMXBeanInterface() tries to find the superclass of a null class.

Probably the getMXBeanInterface() should be made null safe?

AopUtils.getTargetClass(...) is actually supposed to always return a non-null Class. I've made this null-proof along with related pieces of code in JmxUtils.

So the MBean export should work in your case as well now. This fix will be available in tonight's 3.0.2 snapshot already; give it an early try if you got the chance!
