Actually ....

in UIMA 2.10.2 the code at this line is:
*uimaj-core/src/main/java/org/apache/uima/cas/impl/CASImpl.java:3644ff* [1]
```
@Override
public final int ll_getFSRef(FeatureStructure fsImpl) {
if (null == fsImpl) {
return NULL;
}
final FeatureStructureImpl fsi = (FeatureStructureImpl) fsImpl;
if (this != fsi.getCASImpl()) {
if (this.getBaseCAS() != fsi.getCASImpl().getBaseCAS()) {
// https://issues.apache.org/jira/browse/UIMA-3429
throw new CASRuntimeException(CASRuntimeException.DEREF_FS_OTHER_CAS,
new Object[] {fsi.toString(), this.toString() } );
}
}
return fsi.getAddress();
}
```
So there *IS* in fact a call to `FeatureStructureImpl.toString()` here!
