optimization: do not start inference to check caught thrown types if there is no thrown list at all (also helps to avoid calculations inside checked expression constraint during java 8 inference)
new inference: do not resolve method calls in lambda return expressions to check isPolyExpression when arguments do not contain potential constrains
new inference: prohibit substitution during checked exception constraint processing
