I'm more inclined to resolve it at the end of the stacktrace: when the
parameter is null, it should resolve to the context classloader Gili and
Cameron proposed. This way no more null pointers.

looked at the code and i don;t think this will work:
private PackageResource(final Package basePackage, final String path,
final Locale locale,
final String style)
{
packageClass = basePackage.getClass();
and use that packageClass later on:
this.resourceStream =
Application.get().getResourceStreamLocator().locate(
packageClass.getClassLoader(), absolutePath, style,
locale, null);
Because the class that is used there is the the Package.class (the one
of the system classpath)
its a pitty that this: ClassLoader.getCallerClassLoader() is hidden
from use to call..
or else we could do:
private PackageResource(final Package basePackage, final String path,
final Locale locale,
final String style)
{
packageClass = ClassLoader.getCallerClassLoader();
I think the only way is to refactor PackageResource for this
And give us a class instead of a package.

The code that worked in the morning, retrieved from HEAD, does not
work anymore now.
Just a call to DatePicker resources produces a stacktrace on the
appserver console.
The stacktrace below appears for me for every datapicker resource
referenced from generated HTML page. My code has not changed - worked
in the morning with HEAD.
Now it stopped.
I am using eclipse + Jetty
