Annotations on union types where the classes in the union have a declaration annotation #384

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Cannot write annotations on a union type if the types in the union have 
declaration annotations on their type definitions.

For example, (full example attached)
...
        } catch (@NonNull InnerException1 | @NonNull  InnerException2 e) {
        }
...

@PolyUIType
    class InnerException1 extends Exception {}

@PolyUIType
class InnerException2 extends Exception {}

What steps will reproduce the problem?
 javacheck -processor NullnessChecker UnionTypeBug.java  -AprintErrorStack
What is the expected output?
no warnings

What do you see instead?
error: TypeFromElement.getLocationTypeATM: only declared types and arrays can 
have annotations with location; found type: InnerException1 | InnerException2 
location: INNER_TYPE
