Class 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 Server elements.
