Hi, in the Hecl programming language, I do this:
public String toString() throws HeclException {
Vector v = ListThing.get(new Thing(new HashThing(val)));
ListThing newthing = new ListThing(v);
return newthing.toString();
}
Apparently, that should generate a warning or throw an error, because toString
isn't supposed to throw an exception... "regular" java says this:
./com/dedasys/hecl/HashThing.java:140: toString() in com.dedasys.hecl.HashThing
cannot override toString() in java.lang.Object; overridden method does not throw
com.dedasys.hecl.HeclException
public String toString() throws HeclException {
^
Thanks,
Dave

public String toString() throws java.io.IOException
{return "";}
}

This patch can cause an ICE when the super-class is byte-compiled.
If a byte-compiled method M in a super-class throws exception X,
we try to emit an erroneous error message that M can't throw X
(because we don't analyze the bytecode). Worse, because M
doesn't have DECL_FUNCTION_WFL set, we get an ICE in parse_error_context.
The problem is check_interface_throws_clauses, which seems to be doing way
too much work ... it should be not be checking that
"The exception must be a subclass of an exception thrown" in super-classes.

------- Comment #7 from daney at gcc dot gnu dot org 2007-01-30 01:53 -------
In 4.3.0 this is correctly flagged as an error. With the testcase in comment
#1 we get:
$ gcj -o t --main=t t.java
t.java:3: error: Exception IOException is not compatible with throws clause in
Object.toString()
public String toString() throws java.io.IOException
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1 problem (1 error)
