IXMLException, java.io.Serializable

public class NetKernelError
extends java.lang.Error
implements IXMLException

NetKernel exception is a generic exception class used for most exceptions in the NetKernel. It is nestable and allows multiple exceptions to be nested at any depth. Its most important characteristic is that its state can be recursively dumped as XML giving a clear picture of an exception scenario is a document.
