Hi,
I have a small template of this and will post it where you want me
to ;)
This afternoon, I analyzed stack trace and found some "strange" code
in CompilingClassLoader GWT class (http://code.google.com/p/google-web-
toolkit/source/browse/releases/1.5/dev/core/src/com/google/gwt/dev/
shell/CompilingClassLoader.java ):
@Override
protected synchronized Class<?> findClass(String className)
throws ClassNotFoundException {
if (className == null) {
throw new ClassNotFoundException("null class name",
new NullPointerException());
}
// Don't mess with anything in the standard Java packages.
//
if (isInStandardJavaPackage(className)) {
// make my superclass load it
throw new ClassNotFoundException(className);
}
....
}
As far as I understand, every class (and annotations) from java and
javax package are not managed by this class loader, which could lead
to the issue.
I still have to validate this analysis by debugging this method step
by step.
If I am right, I will open an issue about it in GWT project.
Regards
Bruno
