One interesting scenarios was observed when Java applications generate excessive amount of finalizable objects whose classes have non-trivial Java finalizers. A Java finalizer performs finalization tasks for an object. It’s the opposite of a Java constructor, which creates and initializes an instance of a Java class.<p><a href="http://jinwoohwang.sys-con.com/node/995699" target="_blank">read more</a></p> Thu, 16 Jul 2009 23:45:00 EDT http://jinwoohwang.sys-con.com/node/995699 http://jinwoohwang.sys-con.com/node/995699#feedback http://jinwoohwang.sys-con.com/node/921279 We can visualize resource starvation using an elaborate rendition of the Dining Philosophers Problem. This classic metaphor of resource allocation among processes was first introduced in 1971 by Edsger Dijkstra in his paper “Hierarchical Ordering of Sequential Processes.” It’s been a model and universal method for verifying theories on resource allocation ever since.<p><a href="http://jinwoohwang.sys-con.com/node/921279" target="_blank">read more</a></p> Thu, 16 Jul 2009 18:45:00 EDT http://jinwoohwang.sys-con.com/node/921279 http://jinwoohwang.sys-con.com/node/921279#feedback
