Adds an exclusion rule to this descriptor. When choosing whether a class/method is to be insturmented, if exclusion rule matches, that class/method will be skipped from instrumentation.
In general Exclusion rules are more powerful than inclusion rules. That is, if for some reason two similar rules are assigned to both exclusion and inclusion rules, exclusion rule will win.
@param rule A Exclusion rule, that is to be added to this descriptor
@exception JiapiException thrown if there's a syntax error in rule
