Hi,
I'm getting a null pointer exception when unmarshalling xml to classes
generated from using the source generator. This exception only happens
if two threads are trying to unmarshal a document at the same time. One
of the threads will succeed and one will fail with this exception. As
far as I can tell it only happens the first time I try this after I
start the JVM. After the initial error everything works fine. I'm using
castor 1.0.
I'm using the static Unmarshaller.unmarshal(Class, Node) method.
Here's the stack trace:
java.lang.NullPointerException
