Memory Leak can be identified by collecting verbose gc logs. By adding the jvm argument -verbose:gc this will collect GC occupancy information. usually the output of this will be written in the native_stderr.log file or file where stderr has been redirected. Once the usage is over. Load the file in http://www.ibm.com/developerworks/java/jdk/tools/gcmv/ This tool will help you in identification of leaks and GC behavior throughout the life span of the application. Hope this will be helpful for you.
