So, I’m trying to fix a bug on a fairly complex Spring based webapp. The bug is a NullPointer Exception, but, rather unhelpfully, it’s not returning a stacktrace or anything similarly helpful to let me know exactly where it is occurring.

Stepping through the execution of the programme with IntelliJ shows that the exception is occurring in a Spring Proxy object: $Proxy338 , but doesn’t show the proxy code.

I’m sorry for being so vague: The error reporting on this bug is pretty unhelpful. Any suggestions for how I should proceed from here would be welcome: should I be looking for AOP/transaction code which is producing the failing proxy? Is there more information I could gather with IntelliJ which would let me pinpoint exactly what is going on?

    You could also try retrieving the proxied object to see where exactly the NullPointerExeption is thrown.

    To get the proxied object: 

    ((Advised)yourProxy).getTargetSource().getTarget();
