Error Serializing Arrays with Null Values

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create class A with an array of Strings
2. Create an object of A populating an array where at least one of the strings 
is null
3. Serialize the object on the client

What is the expected output? What do you see instead?
SEVERE: (TypeError) : Cannot read property 'length' of null
com.google.gwt.core.client.JavaScriptException: (TypeError) : Cannot read
