Class JreMemoryLeakPreventionListener
- java.lang.Object

- org.apache.catalina.core.JreMemoryLeakPreventionListener
-
- All Implemented Interfaces:
LifecycleListener
public class JreMemoryLeakPreventionListener extends Object implements LifecycleListener
Provide a workaround for known places where the Java Runtime environment can cause a memory leak or lock files.Memory leaks occur when JRE code uses the context class loader to load a singleton as this will cause a memory leak if a web application class loader happens to be the context class loader at the time. The work-around is to initialise these singletons when Tomcat's common class loader is the context class loader.
Locked files usually occur when a resource inside a JAR is accessed without first disabling Jar URL connection caching. The workaround is to disable this caching by default.
This listener must only be nested within
Serverelements.
