/**
 * An Enum for ClassLoaderCacheOption option.
 * 
 * drools.classLoaderCacheEnabled = <true|false>
 * 
 * DEFAULT = true
 * 
 * When resolving classes on the classpath, drools calls the parent classloader to
 * resolve them. Usually classloaders do not cache results, making compilation very
 * expensive on IO. By default, Drools will cache results of class resolution on the
 * external parent classloader in order to improve compilation performance. This
 * cache can be disabled by setting this option to false.
 * 
 * This option is new to Drools 5.1. Before 5.1, Drools would never cache class 
 * resolution results.
