Actually, there is something we can do. The spec doesn't say that we
can't create subclasses of the provided exception classes, so we can
override the toString() method.
I tried this code
throw new SQLFeatureNotSupportedException("some error message") {
public String toString() {
return "SQLException: " + getMessage();
}
};
and it printed this message
SQLException: some error message
not
java.sql.SQLFeatureNotSupportedException: some error message
