/**
* There is an issue in setNestedProperty/getNestedProperty when the

* but it's an easy mistake to make and this test case ensures that an
* appropriate exception is thrown when a user does this.
* <p>
* The problem is with passing strings of form "a(b)" or "a[3]" to
* setNestedProperty or getNestedProperty when the target bean they
* are applied to implements Map. These strings are actually requesting
* "the result of calling mapped method a on the target object with
* a parameter of b" or "the result of calling indexed method a on the
* target object with a parameter of 3". And these requests are not valid
* when the target is a Map as a Map only supports calling get(fieldName)
* or put(fieldName), neither of which can be further indexed with a
* string or an integer.
* <p>
* However it is likely that some users will assume that "a[3]" when applied
* to a map will be equivalent to (map.get("a"))[3] with the appropriate
* typecasting, or for "a(b)" to be equivalent to map.get("a").get("b").
* <p>
* Here we verify that an exception is thrown if the user makes this
