java - Selenium ElementNotVisibleException is an instance of InvalidStateException -

i'm trying catch invalidstateexception (and exception!) code throwing out elementnotvisibleexception , still being caught. know problem because did this:

try{     thrown new elementnotvisibleexception("why???"); } catch(invalidelementstateexception e){     system.out.println("welp, sucks."); } 

and, welp, sucks.

selenium javadocs doesn't list elementnotvisibleexception subclass of invalidelementstate exception, yet java seems think case. can enlighten me/suggest workaround? thanks!

oh, , i'm using java 7, selenium 2.46.

elementnotvisibleexception subclass of invalidelementstateexception, elementnotvisibleexception is invalidelementstateexception. expected behavior.
