FunctionThe thread snapshot used to generate the current moment of the virtual machine (commonly referred to as a threaddump or Javacore file). A thread snapshot is a collection of method stacks that each thread in the current virtual machine is executing, and the primary purpose of generating the thread snapshot is to locate the cause of a long pause on threads, such as inter-thread deadlocks, dead loops, long waits that are caused by requests for external resources, and so on, which are common

In Java development, we often have to deal with various exceptions, we typically get exception information with e.tostring () or e.getmessage (), but sometimes there is a lot of information in the exception stack, such as throwing an exception with the following code: Try{ Code throws Someexception } Catch(Someexception e) { Throw NewMyException ("Caught some exception", e); } In this case, the e.tostring () or e.getmessage () is not able to get all
