implements org.apache.avalon.framework.thread.ThreadSafe

SystemPropertyModule is an JXPath based InputModule implementation that provides access to system properties. JXPath allows to apply XPath functions to system properties. If there is a security manager, its checkPropertiesAccess method is called with no arguments. This may result in a security exception which is wrapped into a configuration exception and re-thrown.
