The state of the thread is a very important thing, so the threads dump will show these states, through the analysis of these states, can get the health of the thread, and then discover possible problems.

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 store it in a heap dump file, providing
