Exceptions capture a new stack trace for each instantiation, so they're
not often equal even if their inputs all seem equal.
I wasn't aware of that. I thought the stack trace collection would
happen at the point where it's being thrown and not when an exception is
being instantiated. Now that you and Kabir mentioned it, I went and had
a look at the Throwable javadoc and it does clearly state this.Thanks!
