/**
* <pre>
* Purpose
* This test verifies the behavior of the MarshalInputStream.resolveClass
* and MarshalInputStream.resolveProxyClass protected methods when
* a call to the RMIClassLoader.loadClass method throws an exception.
*
* Test Cases
* This test iterates over a 4-tuple. Each 4-tuple denotes one test case
* and is defined by the cross-product of these variables:
* String loadClassExceptionName
* Object transferObject
* boolean callUseCodebaseAnnotations
* String readAnnotationReturnVal
* where loadClassExceptionName is restricted to class names and
* subclass names of:
* MalformedURLException
* ClassNotFoundException
* RuntimeException
* Error
* transferObject is one of:
* a File object
* a dynamic proxy for FakeInterface
* callUseCodebaseAnnotations is one of:
* true
* false
* and readAnnotationReturnVal is one of:
* null
* "fakeCodebase"
*
* Infrastructure
* This test requires the following infrastructure:
* 1) FakeRMIClassLoader
* -extends RMIClassLoaderSpi
* -loadClass method checks arguments and then
* throws loadClassExceptionName
* 2) FakeMarshalInputStream
* -extends MarshalInputStream
* -readAnnotation method returns value passed to constructor
* 3) FakeInterface
* -an interface which declares no methods
*
* Actions
* For each test case the test performs the following steps:
* 1) construct a MarshalOutputStream, passing in a ByteArrayOutputStream
* and an empty Collection
* 2) write transferObject to the MarshalOutputStream
* 3) construct a ByteArrayInputStream from ByteArrayOutputStream byte array
* 4) construct a FakeMarshalInputStream, passing in ByteArrayInputStream
* and readAnnotationReturnVal
* 5) if callUseCodebaseAnnotations is true, call
* MarshalInputStream.useCodebaseAnnotations method
* 6) communicate expected arguments and loadClassExceptionName to
* FakeRMIClassLoader using static variables in FakeRMIClassLoader
* 7) attempt to read from the FakeMarshalInputStream
* 8) assert that arguments passed to FakeRMIClassLoader are correct
* 9) assert the exception denoted by loadClassExceptionName
* is thrown directly
* </pre>
