Section 2.2.1 says:
Almost any Java type may be a bean type of a bean:
• A bean type may be an array type.
A type variable is not a legal bean type. A parameterized type that contains a wildcard type parameter is not a legal bean type.
This should be clarified that array types that have a type variable or a parameterized type that contains a wildcard type parameter as the array's component type are also not legal bean types.
Also, all other sections that mention type variables/wildcards should also be reviewed and, if necessary, updated to also specifically mention array types with these kinds of component types.
