tc Server VCAC must be configured with memory leak protection.

Description
The Java Runtime environment can cause a memory leak or lock files under certain conditions. Without memory leak protection, tc Server VCAC can continue to consume system resources that will lead to OutOfMemoryErrors when reloading web applications. 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 JreMemoryLeakPreventionListener class is designed to initialize these singletons when Tomcat's common class loader is the context class loader. Proper use of JRE memory leak protection will ensure that the hosted application does not consume system resources and cause an unstable environment.
