The method clear() is *optional* in the java.util.Map contract, so the
current behaviour is spec compliant. The TCK tests (those that MyFaces
has to pass to be certified by sun) require this exception to be
thrown. So this is why the method is throwing such an exception. The
JSF 1.2 expert group has been encoraged to make the implementation of
the clear() method and others (e.g. putAll()) required, so maybe this
behaviour will be backported to the JSF 1.1 implementation of MyFaces
in the future.
FYI, the RI implementation has the same behaviour, so you should not
use this method now...
