This tool groups the stack lengths of each thread in a thread dump into categories for efficient analysis and optimization.
Knowing the length of a thread's stack trace can be important, as it provides information about the depth of function or method calls within that thread's execution. The length of a thread's stack trace can be an indicator of potential issues, such as stack overflows, which occur when a program exceeds the maximum amount of stack memory allocated for a particular thread. If the length of a thread's stack trace exceeds the maximum amount of stack memory allocated, it can lead to unpredictable behavior, including crashes and memory corruption.
