public class NonLockingJarUrlConnection
extends JarURLConnection

This is copied from Classwords 1.1 org.codehaus.classworlds.uberjar.protocol.jar.JarURLConnection so that an additional dependency does not need to be added to plugins. The formatting is left as is to reduce the diff.

The setupPathedInputStream() method has been modified to improve the speed of resource lookups. It now uses a ZipEntry to get random access to entries in the JAR.

This change removes the ability for this connection class to load resources from JARs nested inside the outer JAR. This is not used in atlassian-plugin because the inner JAR loading is handled by PluginClassLoader.
