It seems there is no way to identify classes (java) that are Exceptions.
Even the one that are used.
There are ThrownException / DeclaredException / CaughtException , all
pointing to the exceptionClass, but there is no opposite property in the
exception class that one could use to test whether a given class is used
as an exception.
So the only way is to test whether Exception is an ancestor of a given
class ?

Indeed. It would be cool to get opposites for the exceptionClass
properties. So, we would have FAMIXClass>>thrownAsException,
FAMIXClass>>declaredAsException, FAMIXClass>>caughtAsException. This
would also imply that we would define the implementation of
exceptionClass in all subclasses of Exception.

Right now, we have
FAMIXException>>exceptionClass
<MSEProperty: #exceptionClass type: #FAMIXClass>
^ exceptionClass
And then we have three subclasses: FAMIXCaughtException,
FAMIXDeclaredException, FAMIXThrownException.
At the moment, exceptionClass does not have an opposite, but we should
add one. Like this we would know if a class is caught, declared or
thrown. But, to know that we would need define three properties in
FAMIXClass, and to redefine the exceptionClass in the three subclasses
of FAMIXException such that the declaration points the opposite to the
right FAMIXClass property.
So something like:
FAMIXDeclaredException>>exceptionClass
<MSEProperty: #exceptionClass type: #FAMIXClass opposite:
#exceptionsWithClassAsDeclared>
...
FAMIXClass>>exceptionsWithDeclaredClass
<MSEProperty: #exceptionsWithClassAsDeclared type:
#FAMIXDeclaredException opposite: #exceptionClass>
...
Cheers,

what do you mean by that sentence because I could not get it clear enough.
