Jackson Core TypeReference init will throw a ArrayIndexOutOfBoundsException quieltly

the exception stack is like blow, and we konw The frequent throwing of exceptions can impact system performance. what can we do about this ?

"main@1" prio=5 tid=0x1 nid=NA runnable

And the test case is very simple:

public class ATest {
    public static void main(String[] args) {
        String str = "{\"aa\":\"bb\"}";
        try {
            Object o = JacksonMapper.getInstance()
                    .readValue(str, new TypeReference<Map<String, String>>() {
                    });
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
