Class Unbox.WebSafeState

java.lang.Object

org.apache.logging.log4j.util.Unbox.WebSafeState

Enclosing class:

Unbox

private static class Unbox.WebSafeState
extends java.lang.Object

State implementation that only puts JDK classes in ThreadLocals, so this is safe to be used from web applications. Web application containers have thread pools that may hold on to ThreadLocal objects after the application was stopped. This may prevent the classes of the application from being unloaded, causing memory leaks.

Such memory leaks will not occur if only JDK classes are stored in ThreadLocals.
