JDK-4358512 - Classes loaded through reflection produces InvalidJarIndexException errors
Description
It is possible to chain jar files using their index files such that a lookup of 
a resource starting at the root jar would cause the program to hang 
indefinitely. The problem occurs because the lookup of jar files fails to skip 
jar files that have already been searched during the current lookup. This bug 
occurs for jdk1.3 on solaris and win32 (NT)

The attached code illustrates the problem. To run the code,
1. Set the classpath to .:a.jar:b.jar:c.jar
2. java c.A
