A DESCRIPTION OF THE PROBLEM :
The java.lang.reflect.GenericArrayType javadoc states, "{@code GenericArrayType} represents an array type whose component type is either a parameterized type or a type variable."  This is incorrect: the component type can also be another GenericArrayType.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the test case, and observe that a GenericArrayType can have another GenericArrayType as component type.
2. Read the java.lang.reflect.GenericArrayType javadoc comment.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The documentation lists GenericArrayType as a possible kind of component type.
ACTUAL -
The documentation does not list GenericArrayType as a possible kind of component type.

REPRODUCIBILITY :
This bug can be reproduced always.
