Description:
Compiler goes into infinite loop for the following Cyclic inheritance in TypeParameter bounds Negative test case .TypeParameters with ArrayType bounds are not allowed and the compiler should be reporting unexpected type and cyclic inheritance error respectively.


<code>
bash-3.00$ cat TypeParamsWithArrayBounds.java
class TypeParamWithArrayBounds<R extends S[],S extends R[]>{
}



</code>
Compilation result is :
<output>
TypeParamsWithArrayBounds.java:1: unexpected type
found : S[]
required: class
class TypeParamWithArrayBounds<R extends S[],S extends R[]>{
                                          ^
TypeParamsWithArrayBounds.java:1: unexpected type
found : R[]
required: class
class TypeParamWithArrayBounds<R extends S[],S extends R[]>{
                                                        ^
