Here is the code from where the error comes from
@Override

logger.trace("Entering OSGiServiceBean : create() with parameter");
try {
BundleContext context = ctx;
if (context == null) {
context = FrameworkUtil.getBundle(injectionPoint.getMember()
.getDeclaringClass()).getBundleContext();
}
DynamicServiceHandler handler =
new DynamicServiceHandler(context,
((Class)
type).getName(),
filter,
qualifiers,
timeout);
Object proxy =
Proxy.newProxyInstance(getClass().getClassLoader(),
new Class[]
{getBeanClass()},
handler);
////////////////// Error is generated when we call newProxyInstance
//memorize if the handler has been allready stored
if (handlers.containsKey(proxy)) {
handler.setStored(true);
} else {
//map.put() need a correct hashCode() method to use
//see DynamicServiceHandler
handlers.put(proxy, handler);
handler.setStored(true);
}
logger.debug("New proxy for {} created", this);
return proxy;
}
catch(Exception e) {
logger.error("Unable to instantiate {} due to {}", this, e);
throw new CreationException(e); // NPE is reported here
}
