[geos-devel] Exceptions

The exceptions continue to muck with us. Exceptions thrown in geos have 
not been catchable, and are taking down the postgres backend with 
sigabort. I did a grep for "throw" in the source code, and the 
exceptions are a bit of a mishmash. Most of them are of the form,

   throw "PointCoordinateList exception: can't retrieve element\n";

But some are of the form,

   throw new ParseException(e.toString());


   throw ParseException("Expected number but encountered ')'")

So, sometimes we are throwing strings, sometimes we are throwing new 
exception objects and other times just static things?

Anyhow, we have had better luck catching the simple throws (the 
strings). Is there a reason for throwing specially constructed 
exception objects?
