The call succeeds and the content is inserted if the passed array contains only one element. In this case, multiple subsequent calls also succeed, so it would be possible to write a trivial workaround. This, however, may not be effective.

This method is protected, but it call be called from the overridden classes and may be later used in HTMLDocument.

The test application

This is a trivial test case that succeeds on Sun's implementation and prints exception in ours.

AFAICS, this is fixed in CVS HEAD.
