New issue 143 by ilo...@gmail.com: NPE when ByteCodeType.fromLoader is
invoked in an empty Application
http://code.google.com/p/as3-commons/issues/detail?id=143

What steps will reproduce the problem?
1. Create an empty Flex Application
2. Define applicationComplete Handler
3. In handler, execute ByteCodeType.fromLoader(this.loaderInfo)

What is the expected output? What do you see instead?
The expected would be ByteCodeType loading the classes successfully. I get
an error instead.

TypeError: Error #1009: Cannot access a property or method of a null object
reference.
