A Classic tag handler exists in legacy code. The author wrote a handler that evaluates its tag body a hundred times, to be used in
testing other tags that produce random content.
What is incorrect about the code?
A. Tag handlers are not
thread safe, so the iterationCount can become out of sync if multiple users are reaching the page at the same time.
B. The doAfterBody method is never being called because it is not part of the tag handler lifecycle. The developer should have extended the IterationTagSupport class to include this method in the lifecycle.
C. The doTag method should be doStartTag. As written, the default doStartTag of TagSupport is called which simply returns SKIP_BODY, causing doAfterBody to never be called.
D. When doAfterBody returns EVAL_BODY_AGAIN the doTag method is called again. The doTag method resets iterationCount to 0, resulting in an infinite loop and a java.lang.OutOfMemoryError is thrown.
Answer is C.
here we need to choose correct one or incorrect one??
