There are a handful of places in the JDK where this kind of

of the context in which it is called in general, what exception would
you throw if you find there is no Java client caller? In the current
case the specs for getBundle state that it is the equivalent of
calling the classloader-taking form with the expression
this.getClass().getClassLoader(). But in the current case there is no
this, no current class and no current classloader - so what exception
do you throw? "new RuntimeException("Expected Java caller not found")?
I don't think throwing MissingResourceBundleException is the right way
to go here because it hides the mis-use of this API.
For this specific case it probably has to be treated as if the caller's
loader is the boot class loader. In that case, MissingResourceException
may be thrown (I can't tell from the original mail if the resource
bundle is found when the loader is specified as null, I assume not).
