[JWebUnit-users] Re : Attempted to refresh a page using an ImmediateRefreshHandler which could have caused an OutOfMemoryError Please use WaitingRefreshHandler or ThreadedRefreshHandler instead

[Julien H. <he...@ya...>]

Hi Jason,

Currently there is no way to change the refresh handler. There is a long 
standing issue about accessing HtmlUnit internals from JWebUnit API. At first it 
was a choice to prevent user to call HtmlUnit specific API and prevent easy 
switch to another testing engine but now we admit there are cases where it 
should be possible.

We are waiting for contribution in this area.

Regards,

Julien
