## Description
> Please describe your concern in detail!
In JML you can't use userdefined \sorts from .key files
```
\javaSource ".";
\sorts{
Tupel;
}
\chooseContract
```
```java
class A{
\\@ public ghost \dl_Tupel t;
}
```
## Reproducible
always
### Steps to reproduce
1. Create the .key and .java file mentoned above
2. Put both in the same directory
3. Load the .key file in KeY
> What is your expected behavior and what was the actual behavior?
### it should load, actual behaviour
