Eclipse memory Analyze is a Java heap dump file analysis tool that can help you to identify and reduce memory vulnerabilities.OverviewFor large JAVA applications, fine testing is also hard to block all vulnerabilities, even though we have done a lot of good work during the testing phase, many problems are exposed in the production environment and are difficult to reproduce in a test environment. The JVM is able to record some of the operational state of the system when the problem occurs and sto
