Hi Charles,
I just checked the code with the stack trace, and found this issue may
caused by the java.lang.NullPointerException.
Here is the code snippet of the OsgiComponentResolver.
try {
type = getComponent(name);
} catch (Throwable e) {
throw new IllegalArgumentException("Invalid URI, no
Component registered for schema : " + name, e);
}
The getComponent() method just search the bundle entry for the component.
I have no idea why the NPE will be thrown from this getComponent() method.
