# What problems are there for types in .aj files?

There are several known issues for types contained in .aj files.

- They are not found when using code assist (Ctrl+Space).
- They are not found when using add import (Ctrl+Shift+M).
- They are not found when using organize imports (Ctrl+Shift+O).
- There are no quick fixes available (Ctrl+1).
- They are not included in Java searches.
- They are not included in Call Hierarchy lists.
- It is not possible to run JUnit tests written in .aj files.

AJDT intends to add support for these features in .aj files in future releases.
