I used @QueryParam to inject a char variable in a method of a resource class:
public String getDefault(@QueryParam("letter") char count)
I don't use @DefaultValue. According to the jaxrs 2.0 API javadoc:
If this annotation is not used and the corresponding meta-data is not present in the request, the value will be an empty collection for List, Set or SortedSet, null for other object types, and the Java-defined default for primitive types.
So if I access the method without value in the request, I should get the Java-defined default value of char – \u0000, but what I get is "0"
