Java 9 Dependency Injection

Stack-walking API

To debug exceptions, we look at the root cause of exception by traversing the stack trace. Prior to Java 9, we all used Thread.getStackTrace() to get StackTraceElement objects in the form of arrays.

StackTraceElement: Each element of StackTraceElement is a single StackFrame, which provides details about classname, method name, filename, and line number where the exception was generated. Except for the first StackFrame, all the other elements represent the method invocation call from the starting point of the application to the point where the exception generated.
