Class JreMemoryLeakPreventionListener
java.lang.Object
org.apache.catalina.core.JreMemoryLeakPreventionListener
- All Implemented Interfaces:
- LifecycleListener
public class JreMemoryLeakPreventionListener
- extends java.lang.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.
