November 2008 This document is a guide to help troubleshoot problems that might arise with applications that are developed using the release of Java Platform, Standard Edition 6 (JDK 6 release or Java SE 6 release). In particular, this guide addresses possible problems between the applications and the Java HotSpot virtual machine.
How memory leaks manifest themselves in Java programs Most programmers know that one of the beauties of using a programming language such as Java is that they no longer have to worry about allocating and freeing memory. You simply create objects, and Java takes care of removing them when they are no longer needed by the application through a mechanism known as garbage collection.
