All Implemented Interfaces:

LifeCycle

public class GCThreadLeakPreventer
extends AbstractLeakPreventer

GCThreadLeakPreventer Prevents a call to sun.misc.GC.requestLatency pinning a webapp classloader by calling it with a non-webapp classloader. The problem appears to be that when this method is called, a daemon thread is created which takes the context classloader. A known caller of this method is the RMI impl. See http://stackoverflow.com/questions/6626680/does-java-garbage-collection-log-entry-full-gc-system-mean-some-class-called This preventer will start the thread with the longest possible interval, although subsequent calls can vary that. Recommend to only use this class if you're doing RMI. Inspired by Tomcat JreMemoryLeakPrevention.
