Any empty url-parameter will make wicket 1.5 crash
--------------------------------------------------
Key: WICKET-4398
URL: https://issues.apache.org/jira/browse/WICKET-4398
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.5.3
Reporter: Johannes Odland
Adding an empty parameter to the query string will make wicket crash.
http://www.example.com/?oneParam&;
How to reproduce in test:
PageParameters params = new PageParameters();
params.set("","");
params.getAllNamed();
Cause:
Wicket accepts empty parameters, but when encoding the url for a rendered page
it will call params.getAllNamed().
params.getAllNamed() instantiates new NamedPairs, which calls Args.notEmpty()
on the key during instantiation, causing the application to crash.
The NamedPair constructor should probably allow empty string as a key, and call
Args.notNull() on the key in stead.
