NPEs when locating resources after upgrading to Wicket 6.13.0

Hey all,

I just tried to upgrade to Wicket 6.13.0 because of the new JQuery version
packaged with it. It breaks some of our resource mounting functionality
that has been working since 1.4x and some package resources cannot be found
anymore. Have there been changes to resource mounting in this release?

A sample exception looks like this:

org.apache.wicket.WicketRuntimeException: An error occurred while
> generating an Url for handler
> 'ResourceReferenceRequestHandler{resourceReference=scope:
> com.synexit.friendsic.view.wicket.staticcontent.StaticContentBase; name:

The resource is there and works perfectly with Wicket 6.12.0.

Any ideas?

Cheers,

Hey Martin,

I don't have time to create a quickstart at the moment. If you can't find
the problem without it I'll try to do it in the next days.

The resource is definitely there and downgrading to 6.12.0 fixes the
problem immediately.

Re: NPEs when locating resources after upgrading to Wicket 6.13.0

Posted by Martin Grigorov <mg...@apache.org>.

Please put a breakpoint at
https://github.com/apache/wicket/blob/wicket-6.x/wicket-core/src/main/java/org/apache/wicket/request/resource/PackageResource.java?source=cc#L431

It seems " /images/alt_neu_v2.jpg; locale: null; style: null; variation:
null" does not exists. Only in this case the resource stream would be null.

Unfortunately this happens in a private method and I don't see how to
workaround it.
Please create a ticket with a quickstart.

Hi,

Please check your logs for : "Argument 'delegate' may not be null."

This is what

should actually throw.

I am looking why it could be null.
