Description

Method ignores exception in clazz constructor, and if any - throws exception later, when try find constructor with args matches collection items.

public static <T> T asType(Collection col, Class<T> clazz) in DefaultGroovyMethods.java, line 10623:

DefaultGroovyMethods.java

        Object[] args = {col};
        try {
            return (T) InvokerHelper.invokeConstructorOf(clazz, args);
        } catch (Exception e) {
            // ignore, the constructor that takes a Collection as an argument may not exist
        }

In my opinion, should ignore only if such constroctor not found
