NPE when ByteCodeType.fromLoader is invoked in an empty Application #143

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
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.
