Re: [Htmlunit-user] htmlunit sometimes hanging

[Marc G. <mgu...@ya...>]

Hi

look carefully at the stack: it doesn't hang, it is waiting because 
you're using the WaitingRefreshHandler. Are you sure that this refresh 
handler makes sense for you? According to your question, it is probably 
not the case ;-)

Cheers,
Marc.
