[jibx-users] 1.2 Potential Bug

[Smith,Drew <Drew.Smith@Cerner.com>]

Per my previous email, I've been trying to compile bindings from different archives using the 1.2 <include precompiled="true"/> feature.  That part seemed to work, it imported the mappings and didn't try to compile them again, but it appears that this brought another error when compiling the parent object containing the included mappings:

Error running binding compiler

org.jibx.runtime.JiBXException: Classloader conflict for binding 'common_message
_binding' - factory does not implement required interface
        at org.jibx.runtime.BindingDirectory.getFactory(BindingDirectory.java:27

        at org.jibx.binding.Compile.compile(Compile.java:212)
        at org.jibx.binding.Compile.main(Compile.java:374)

common-message-binding is the name of the binding file obviously:

public class JiBX_common_message_bindingFactory extends BindingFactoryBase implements IBindingFactory
{
       private static IBindingFactory m_inst;
}

I ran the compiler command with the verbose command, and it definitely is pulling in the 1.2 BindingDirectory, BindingBuilder, etc. classes, and the including, previously compiled binding was run with the same.

Looking at the BindingDirectory code, we see this snippet:

if (result instanceof IBindingFactory) {

That if statement will evaluate to false if result == null, and there is no null check, so the printed stack trace might not be the actual error.  Also, is instanceof the best evaluator?  Wouldn't it be better to use the reflections api with something like:

Class clazz = Class.forName(className);
List<Class> interfacesList = Arrays.asList(clazz.getInterfaces());
if(!interfacesList.contains(IBindingFactory.class))
{
	throw new Exception(clazz.getName() + " does not implement " + IBindingFactory.class.getName());
}

Or

if (result != null && result instanceof IBindingFactory) {

Thanks,
Drew
